RESUMO
Wolff-Parkinson-White (WPW) syndrome is defined as the presence of an accessory atrioventricular pathway which is manifested as delta waves and short PR interval on electrocardiography (ECG). However, some WPW cases do not have typical findings on ECG and may remain undiagnosed unless palpitations occur. Sudden cardiac death may be the first manifestation of WPW and develops mostly secondary to degeneration of atrial fibrillation into ventricular fibrillation. In this report, we present a case of undiagnosed WPW with minimal preexcitation on ECG and who suffered an episode of malignant arrhythmia as the first manifestation of the disease.

The aim of the present study was to investigate degree of erectile dysfunction (ED) in males with slow coronary flow (SCF). Endothelial dysfunction was proposed to be the underlying mechanism in both diseases. A total of 29 male patients with slow coronary flow (mean age 45+/-7 years) and 23 male patients with normal coronary arteries (mean age 48+/-12 years) were included in the study. The severity of ED was determined according to the International Index of Erectile Function (IIEF) questionnaire. Mean IIEF scores in patients with SCF and control group were determined as 20.97+/-7.26 and 25.26+/-5.17, P=0.016. ED was detected in 45% (n=13) of SCF patients and 35% (n=8) of the control group (P=0.035). There was a negative correlation between the mean TIMI frame count and IIEF score between patients with SCF and controls (r=-0.31, P=0.029). These data suggest that ED is observed more frequently in patients with SCF phenomenon compared to patients with otherwise normal coronary angiograms.
