Introduction: Arrhythmias are a type of heart disease, and the tests are usually very much related to the electrocardiogram. So what are the tests for arrhythmia?
Arrhythmias are caused by abnormal changes in the normal rhythm of the heart, mainly manifested by arrhythmias that are faster than the normal heart rate, so they are called tachyarrhythmias. The symptoms of arrhythmia are palpitations, panic attacks, chest tightness, dizziness, etc. If the arrhythmia is severe, patients may experience chest pain and difficulty breathing.
Arrhythmia examination methods
1.Electrocardiogram
The electrocardiogram (ECG) is a long-duration recorder called Holter, which is a small portable recorder that is used to record the ECG continuously for 24 hours and is carried by the patient during meals, sleep and work. It can understand the relationship between arrhythmia attacks and daily activities, diurnal characteristics, etc.
2.Electrocardiogram
This is one of the most commonly used and important non-invasive tests. Some ventricular arrhythmias, atrioventricular block, atrial fibrillation, bradycardia or tachycardia can be diagnosed by electrocardiogram.
3.Exercise test
It is the simultaneous observation of the patient’s ECG during exercise, and is suitable for patients who have palpitations during exercise.
4.Clinical cardiac electrophysiological examination
It is an invasive test in which several multi-electrode catheters are inserted through veins or arteries and placed in different parts of the heart chambers to record electrical activity. Patients undergo this test for three purposes: to confirm the diagnosis of arrhythmias and their types, to understand the origin and mechanism of arrhythmias, to identify and treat certain tachycardias, and to determine the prognosis.
5.Esophageal electrocardiogram
The posterior wall of the left atrium is adjacent to the esophagus, and the location of the esophageal electrodes is at the level of the left atrium, so special electrodes can be inserted into the esophagus to record clear atrial potentials, which can help the diagnosis of certain specific types of arrhythmias.
How to prevent arrhythmias
1. Do not neglect regular medical checkups. Many patients with arrhythmias do not have typical symptoms such as panic attacks and chest tightness, and it is only during medical checkups that the arrhythmia is discovered. The temporarily asymptomatic arrhythmia is just as harmful to the body and can harm the heart or cause strokes, and in a state of severe fatigue may suddenly occur serious arrhythmias and even sudden death.
2, exercise should be moderate. For patients with arrhythmias, it is never the more exercise the better for the body, in the spirit of the principle of “move according to your ability”, do not force exercise or over-activity. The elderly should take a walk, play taijiquan and other softer exercises.
3, after the discovery of arrhythmia, according to medical advice, and not arbitrarily choose drugs, or the condition of a slight improvement in their own discontinued drugs, should consult with a doctor before making a decision.
4.Avoid sudden stimulation by cold or heat, be careful of colds, and the water temperature should not be too high or too low when bathing.
5. Do not drink alcohol in excess, and quit smoking and stay away from second-hand smoke. These factors may make sympathetic excitation, and lead to abnormal heart conduction.
6, get along with people tolerant and open-minded, avoid mood swings, do not sulk, and can not be angry or overly nervous.
7, do not overeat, eat more fresh fruits and vegetables, and drink less coffee, strong tea and other beverages.
8, actively treat the original disease, which is a very important part of the prevention of arrhythmia.
9, keep a good sleep, avoid overwork. Long-term exertion is one of the most common causes of arrhythmias.
