Abstract

In a prospective study conducted over 4 months at the Accident and Emergency Department, 21 patients with 24 episodes of spontaneous paroxysmal supraventricular tachycardia (PSVT) were treated with intravenous adenosine at incremental doses of 3 mg, 6 mg, 9 mg and 12 mg until termination of the PSVT. There were 6 males and 15 females. The mean age was 54 +/- 17 years (range from 23 to 83 years). The mean QRS rate was 171 +/- 21 per minute. When data were expressed in a cumulative manner, the response to intravenous adenosine 3 mg, 6 mg, 9 mg and 12 mg in the 24 episodes of PSVT were 5 episodes (21%), 16 episodes (67%), 20 episodes (83%) and 20 episodes (83%) respectively. Adverse effects were present in 10 episodes (42%) of the PSVT. They were all mild and transient, lasting less than 1 minute.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
