Arrhythmias - Supraventricular and Ventrical Tachycardia
In cases of supraventricular tachycardia (SVT), the heart's normally precise heart rate speeds up, sometimes as fast as 150 to 200 beats a minute. The heart can return to its normal rate (60 to 100 beats a minute) on its own or through treatment. Symptoms of SVT can include palpitations, light-headedness and chest pain. In some instances there may be confusion or even a loss of consciousness.
In contrast to supraventricular tachycardia which occurs in the upper chambers of the heart, arrhythmia caused by ventricular tachycardia starts in the lower part of the heart. The fast rhythm of the ventricles can lead to ventricular fibrillation, which can be life threatening. Symptoms of ventricular tachycardia include palpitations, dizziness or lightheadedness, shortness of breath, chest pain, nearly fainting or actually fainting.
