[Primary vasospastic angina pectoris: relations between manifestations of ischemia and presence of ventricular arrhythmia].
24-hour ECG monitoring was performed in 12 patients with primary vasospastic angina (PVA). Angiography revealed a predominant lesion to a single coronary vessel (83%). There were 64 episodes of ST-segment changes (46 elevations and 18 depressions) during the monitoring that lasted 388 hours and 54 minutes. Ventricular arrhythmias were concomitant in 34% of the episodes. Ventricular arrhythmia significantly more frequently occurred when an ischemic episode lasted more than 5 minutes. No significant relation was established between the presence of ventricular arrhythmia and other indicators of ischemic manifestation.
