Q: What is supraventricular tachycardia? A: Characteristics of supraventricular tachycardia are as follows: Supraventricular tachycardia mainly includes paroxysmal supraventricular tachycardia, autonomous atrial tachycardia and non-paroxysmal borderline tachycardia. Paroxysmal supraventricular tachycardia is a paroxysmal fast and regular ectopic rhythm. It is characterized by a sudden attack and a sudden stop of heart beat. Autonomous atrial tachycardia refers to the atrial tachycardia caused by a moderate increase in the intensity of self-discipline in the atrial ectopic pacemaker and an increase in the frequency of arousal. Non-paroxysmal borderline tachycardia is a tachycardia caused by increased self-discipline in the atrioventricular junction (connected area). The heart rate during the attack is 150 to 250 beats per minute for several seconds, minutes or hours, or several days. Sometimes when the doctor arrives, the attack has already terminated. Panic may be the only manifestation for the attack. In most cases, the presence of the atrioventricular pathway, or the difference in conductivity and refractory function of the atrioventricular node is the basis for the attack of supraventricular tachycardia.   Key words: supraventricular tachycardia; characteristics of supraventricular tachycardia.
I have had three episodes over 3 years. I had another one early this morning.  I took 3 propafenone and my heart rate has been normal all day.  It is 7:20 pm, and my heart rate is back at 156 beats per minute.  Should I take another dose of propafeone or go to the ER?
No extra dose go to e.r.
