Premature beats and unexpected heart block: an unusual mechanism confirmed by ablation.
A 23-year-old, otherwise healthy woman presented with recurrent skipped and rapid sustained heart beats. Her physical examination and echocardiogram were normal. The presenting ECG in Figure 1 shows sinus rhythm, a nonconducted sinus p wave, and premature complexes. Both left bundle-branch block (5 and 6 complexes) and right bundlebranch block (10 complex) morphologies are present. The 5 and 10...

متن کاملNeural Network Classification of Premature Heart Beats
In this paper, we analyse features from R waveform of electrocardiogram (ECG) and arterial blood pressure (ABP) signals for classifying premature heart beats. Detection of these beats is important as they could be a pre-cursor for serious arrhythmias. The fusion of ECG and ABP signals to detect premature heart beats are relatively new as most methods use only ECG signals. Two new features, mobi...
متن کاملSleep and ventricular premature beats.
Sixty-nine 24-hour electrocardiographic monitoring sessions were conducted in 54 ambulatory subjects. Thirty-one had coronary heart disease (CHD); 11 had miscellaneous heart ailments; and 12 were free of any heart disease. Monitoring was accomplished with a miniaturized cassette recorder and ventricular premature beats (VPBs) were analyzed as to incidence and grade. The occurrence of VPBs durin...
متن کاملVentricular echo beats in the human heart elicited by induced ventricular premature beats.
SUMMARY In three patients, all having as their only hemodynamic abnormality an elevated cardiac index at rest, ventricular echo beats could be elicited by ventricular premature beats induced during regular driving of the ventricle. The occurrence of ventricular echo beats was in each case limited to a small delay-range of the premature beat. Retardation of retrograde conduction of the premature...
