Purpose:
Is onset of symptoms in AV nodal re-entrant tachycardia (AVNRT) and accessory pathway-mediated re-entrant tachycardia (AVRT) patients gender-specific?
Methods:
Intra- and inter-gender differences in onset of symptoms and mechanism of supraventricular tachycardia in adult patients undergoing catheter ablation for AVNRT or AVRT (N=230) were documented.
Results:
Women with AVNRT were significantly younger at onset of symptoms compared to men (38+/-18, 51+/-18 years, p=0.01). Male AVNRT patients were significantly older at onset of symptoms compared to male AVRT patients (51+/-18, 25+/-11 years, p=0.04) but there was no difference in women. Symptoms beginning <30 years in men predicted AVRT in 73%, and beginning >or=30 years the predominant mechanism was AVNRT (85%). In women AVNRT was the most likely mechanism independent of symptom onset (>75%).
Conclusions:
Symptoms beginning in patients with AVNRT and AVRT prior to age 30 correlates with a 70% incidence of AVRT in men and a 80% incidence of AVNRT in women. Onset of palpitations >or= age 30 relates to AVNRT in 85% of patients.

Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism, and...
