Previously, these supraventricular tachycardia required long term drug therapy but more recently curative treatment with ablation has been developed. Other times they persist and may require drug treatment or electrical conversion in hospital. Sometimes these episodes are short-lived and terminate spontaneously. This usually causes distressing palpitations often with light-headedness, chest tightness, breathlessness and other symptoms. These are called supraventricular tachycardia (SVT) during which the heart rate can increase quite suddenly to over 200 beats per minute. Other forms of rapid heart beating are not life-threatening in the same way as ventricular tachycardia. Other non life-threatening forms and symptoms which may require drug treatment The most serious cardiac rhythm disturbance is called ventricular fibrillation when the electrical activity is so fast and chaotic that the heart cannot pump any blood.Ĭollapse and sudden death follows unless cardiac pulmonary resuscitation (CPR) and further medical help is provided immediately. When rapid heart beating arises in the ventricles – called ventricular tachycardia – a life-threatening situation can arise. Some forms of rapid heart beating can be life-threatening We consider that the normal heart rate is between 60 and 100 beats per minute but there are many exceptions.Īthletic people may have heart rates less than 60 and all of us can have rates over 100 when we are exercising or under pressure etc. If it is too fast, it is called a tachyarrhythmia or tachycardia. If the heartbeat is too slow, it is called a bradyarrhythmia or bradycardia.
