Supraventricular tachycardia is it? is Heart disease？

Tachycardia is a type of arrhythmia. Tachycardia mainly refers to more than 100 heartbeats per minute, even faster, the fastest can reach 350-600, the most serious tachycardia we called ventricular tachycardia (referred to as VT) or ventricular fibrillation ( referred to as ventricular fibrillation).

The frequency of ventricular tachycardia generally under about 150 per minute, the vast majority of patients under normal circumstances, tolerate a few hours, or more than a dozen hours, longer time the patient may have life-threatening. And if the frequency of ventricular fibrillation per minute to reach 350 to 600, the concept of cardiac arrest is actually the same, are not blood, because the heart's main purpose is for the blood circulation of the blood supply of organs, the heart does not skip people's blood circulation it stopped. Therefore the onset of ventricular fibrillation when patients can not be maintained for several hours, and 15 minutes will not treat patients died.

Difficult to find common electrocardiogram too slow heartbeat

Person's heart rate is called "sinus node" local control, it is like a generator, according to the inherent frequency of issuance of its electrical pulses per minute under 60 ~ 100. Therefore, we say that a normal heartbeat is 60 to 100 per minute, if the number of heartbeats slow over 60, or faster than 100 are arrhythmia. Of which less than 60 the number of heartbeats / minute is slow arrhythmia.

Bradycardia caused by the most common site is the heart of the sinus node and atrioventricular node. If the problem is the sino-atrial node, which is equivalent to a pump to the body of the "generator" lack of motivation, so the various organs of the body's blood supply will be insufficient, the most common is the brain hypoxia.

As regards the atrioventricular node, the most common illnesses is atrioventricular block: above "generator" of the operation is normal, but the station took place in the middle block, electric conduction can not continue, so on the slower heartbeat.

At present, the inspection method is too slow heartbeat is a 24-hour Holter monitoring, but it is very difficult to find common electrocardiogram of paroxysmal cardiac too slow. Because ordinary ECG time was too short, if the heart within 23 minutes in this no problem, the patient can easily be missed a. However, as a result of dynamic electrocardiogram monitoring a long time and have sufficient time to capture the heart of what has gone wrong in the end.
