Heart rhythm disorders
The heart is a real miracle of nature - a complex organ that ensures the life -proof blood supply to the body. Our heartbeat is created by electrical impulses that are generated in the right atrium and forwarded in an even rhythm over the heart muscle. This is how the heart of the respective load adapts - in peace, it makes it slower, faster if they are exhausted, to optimally supply the body with blood. But what if this heartbeat gets out of time?
What are cardiac arrhythmias?
In peace, the heart usually beats about 60 to 70 times a minute. In order for it to pump the blood through the body, electrical impulses are generated that excite the cardiac muscle cells and get them to contract. The clock for these impulses is the sinus node that is in the right atrium. From there, the signals via the atria to the atrioventricular node - a kind of switch between atria and cardiac chambers - are forwarded and finally led into the heart chambers. This ensures that the individual sections of the heart work coordinated. However, if this rhythm gets out of balance, there may be a cardiac arrhythmia disorder.
A distinction is made between different types of cardiac arrhythmia:
👉🏼 Bradycardia
An unusually slow heartbeat, also called Bradycardia, can have various causes. This includes certain drugs, functional disorders of the sinus node or problems with the signal transmission between the atria and the heart chambers (AV node disorders). Typical signs of bradycardia are dizziness, nausea, shortness of breath or a general decrease in physical performance. In some cases, fainting can even occur.
👉🏼 Tachycardia
A tachycardia, i.e. an unusually fast heartbeat, can have different causes depending on the underlying heart disease and occur in the heart at different points. A distinction is made between tachycardia that arise in the atria (supraventricular tachycardia), and those that occur directly in the heart chambers (ventricular tachycardia). The ventricular tachycardia in particular are dangerous because untreated to serious emergency situations such as circulatory arrest and, in the worst case, they can lead to sudden cardiac death.
👉🏼 Ventricular tachycardia
With ventricular tachycardia, the heart chambers beat so quickly that they can no longer fill with blood sufficiently. This leads to rapid heartbeat, dizziness, shortness of breath and breasts. In severe cases, lack of loss or sudden cardiac death. When it comes to chamber fibrillation, the electrical activity of the heart chambers is so uncoordinated that the heart no longer performs effective pumping push. A cardiovascular arrest occurs, which requires immediate resuscitation measures such as cardiac massage and defibrillation.
👉🏼 Supraventricular tachycardia
Supraventricular tachycardia are quick cardiac arrhythmias from the atria, which can lead to rapid heartbeat, dizziness, shortness of breath and chest pain. Although they are rarely life -threatening, they are stressful. The most common forms include AVNRT and AVRT, in which circular excuses with up to 200 strokes per minute arise from changed or additional electrical connections between the atrium and chamber, especially in young, heart -healthy people. Another example is the atrial rag, which is created by a circular excitement around the tricus pidal flap and can increase to over 250 strokes per minute if exhausted. Attach fibrillation is one of the most common rhythm disorders in which chaotic excitement lead to an irregular, often too fast heartbeat.

Cardiac arrhythmia and histamine
Since the discovery of histamine in 1910, it has been known that this substance is not only released in allergic reactions becomes, but also the heart, the Heart muscle as well as the Blood vessels can influence directly. Various studies have shown that histamine Cellular events can trigger in the heart to ultimately abnormal Heart rhythms lead.
The different play in particular Histamin receptors (H1, H2, H3 and H4) a role. H1 receptors on the AV node can Signal forwarding in the heart Change, which affects the cardiac arrhythm directly. At the same time, H2 receptors modulate both the Contraction as well as the Vascular tone, which makes you play an important role in the regulation of the heart function. H3 receptors can be found sympathetic nerve fibers, while H4 receptors are mainly found in immune cells. In the healthy cardiovascular system, the effects imparted by H1 and H2 receptors are strictly regulated on the heart. But with one damaged vascular systemone sick heart muscle Or accompanying Infection and inflammatory reactions as well as Lack of oxygen can vary the sensitivity to histamine considerably. In such cases, both Slowed heart frequencies (bradycardia <60/min) as well as accelerated cardiac arrhythms (tachycardia> 100 rpm) observed. This is particularly relevant in view of the increasing number of cardiac arrhythmias in an aging population. In addition, researching the histamine metabolism in old age and the growing number of cases is moving with Histamine intolerance and Mastocytosis increasingly in focus.
According to data from the University of Erlangen-Nuremberg, around 15 % of the patients showed Immunological hypersensitivity reactions also Heart rhythm disordersthat had to be further clarified. These occurred partly after the Recording of an allergen, in connection with infections or by unknown factors. The severely increased hospital stays are particularly striking because of Atrial fibrillation In the past 20 years - millions of people are affected. While many factors like Age, heart failure Or a better one Diagnosis contribute to the climb, it is becoming increasingly important to patients with a disturbed histamine regulation to identify specifically. Because for them specific therapeutic approaches such as allergen leave, a low -histamine diet or antihistamines could be more effective than the usual treatment strategies in Idiopathic atrial fibrillation.

Causes and risk factors
The possible causes of cardiac arrhythmias are very diverse. Here are some of them:
👉🏼 Basic diseases as the cause of cardiac arrhythmias:
- Coronary heart disease (KHK) and heart attack
- Heart valve diseases
- Heart muscle infections
- Heart weakness (heart failure)
👉🏼 Congenital causes:
- Malformations in the arousal management system
- Inherited cell misalignments in the heart
👉🏼 Other possible causes:
- Thyroid overactive
- Chronic kidney disease
- Diabetes mellitus
- Accidents/injuries from electrical current
- Heart medication & blood pressure lower
- Certain antidepressants, antibiotics & cancer medication
- Hypertension
- Smoking, drug use, excessive alcohol consumption

Diagnosis
Cardiac arrhythmia can be reliably with a Electrocardiogram (EKG) notice. Your electrical heart activity is recorded. If the rhythm disorders only occasionally occur, there is often a Long-term ECG necessary. For this you wear a small EKG device on the belt, which is glued over Electrodes The heart activity measures for 24 to 72 hours. If the Rhythmia As rare as they are not recorded in the long-term ECG, there is the possibility of recording with a "Loop recorder“. An external loop recorder is also carried on the belt and activated by a key pressure, as soon as you feel an irregularity. Alternatively, an implantable loop recorder can be used under the skin-it automatically monitors the heart rhythm for up to three years. In addition to the EKG, further diagnostic methods are available as X -rays Or echocardiography, i.e. an ultrasound examination of your heart.
Diagnostics in the case of histamine -related cardiac arrhythism disorders:
If all previous examinations were inconspicuous and no cause for your symptoms could be found, it is worth it, once Histamine -related causes to consider. Often they are Laboratory values, including the Allergy value ige, unobtrusive. In the next step, a nutrition diary can help: note what you eat and what symptoms occur. In order to test the suspicion of histamine intolerance, you can test for thorough-historical foods and so-called "histamine liberators" that increase the distribution. If the symptoms disappear, this indicates an intolerance. It is important that you find out what food and medication this Histamine equilibrium influence. Before you change your diet, other possible causes should be excluded - this also includes a Medication check and the consideration Mental stress. Because psychological stress or severe pain can also be used Histamine release support financially. You should first discuss all possible changes and abnormalities with your doctor.

Treatment options
Many patients with a harmless cardiac arrhythmia do not require treatment. However, if the disorder occurs more often and affects the quality of life, various therapy options are possible.
👉🏼 Therapy tachykarder cardiac arrhythmia
Medicinal therapy:
- Frequency limitation: Slowing the heartbeat without direct treatment of the rhythm disorder (e.g. for atrial fibrillation).
- Rhythmic therapy: restoration and stabilization of the normal sinus rhythm through medication.
- Catheter ablation:
A cardiac catheter targeted areas of the heart muscle tissue that cause the rhythm disorder. Often even more effective than medication, in some cases (e.g. atrial flutter) even healing. - Defibrillator implantation (ICD) for risk patients: inside:
Protection against sudden cardiac death by cardiac chamber athycardia. In the case of chamber fibrillation, the ICD gives a steering impact to restore the normal heart rhythm.
A implantation types:
- Transvenient: Electrode is inserted into the heart via a vein, defibrillator placed under the skin.
- Subkutan: electrode under the skin, no vein affected → lighter distance if necessary.
👉🏼 Therapy Bradykarder Heart Rhythmia
- Heart pacemaker therapy:
A pacemaker is necessary if the heart rate falls below 40 strokes per minute or long breaks (> 5 seconds) occur. It stimulates the heart and prevents symptoms like dizziness. - Implantation of a pacemaker:
Electrodes are inserted into the right heart via an arm vein (atrium and/or chamber). They record their own heartbeat and give impulses if necessary. The pacemaker is used under the skin or muscle at chest height. Regular checks every 6–12 months, often also by distance from home. Programming can be adjusted individually. After the implantation, a normal life is possible in most cases.
👉🏼 Therapy of histamine -related cardiac arrhythmia
If other causes could be excluded with certainty and the suspicion of histamine-related complaints is increasing, a nutritional and lifestyle adjustment is worthwhile. Experiments largely avoid stress and, if possible, integrate relaxation exercises into your everyday life. You should also switch your diet to "Histamine arm".
