Palpitations are the expression of ventricular ectopic beats or supraventricular arrhythmias [3, 9].
Ventricular arrhythmias occur in 34% of patients with MVP, ventricular ectopic beats being most frequently encountered (66%).
Furthermore, we observed that VT episodes were more frequent in 24 h, had a longer sequence of ventricular ectopic beats
and were faster in non-survivors than in survivors (Table 1).
The weight loss effects of sibutramine must be balanced against the cost of the drug ($108 per month) and possible adverse health effects (increased heart rates, ventricular ectopic beats
, or epileptic seizures).
Electrocardiographic recordings were initially scanned at high speed and subsequently reviewed for more precise analysis by two observers, with the total number of ventricular ectopic beats being determined for each subject.
Simultaneous ABP and ECG monitorings: Hypertensive subjects showed significantly more ventricular ectopic beats than normotensive controls (Table II).
1)(*) SBP = systolic blood pressure; DBP = diastolic blood pressure; VEB = ventricular ectopic beats.
During sinus rhythm inverted T waves in VI-V4 and frequent ventricular ectopic beats were observed.
Frequent ventricular ectopic beats were recorded during 24-hour ECG monitoring.
On admission, the patient showed a prolonged QT interval, ventricular ectopic beats
, and runs of torsades de pointes tachycardia.
