What is the mechanism for the progressive widening of QRS complexes and for the normal narrow QRS complexes observed in the ECG of a 52-yo male with recurrent syncope?

Pacemakers, while uncommon in children, are important devices. Many children with a pacemaker live distant to their cardiac centre and may present to their local hospital. The indications, types and ...

A novel method is presented here to automatically extract the key information from pace-mapping data with automated detection of paced heartbeats from the surface ECG signals, using wavelet detection ...

The ECG obtained 18 days before the patient’s current presentation showed atrial pacing with evidence of extensive myocardial damage from previous infarctions.

It's a type of arrhythmia, meaning the heart rhythm isn't happening in the normal way. Idioventricular rhythm may be seen ...

During the original ECG recording, the VT rate was just above the programmed device base rate. Device interrogation showed that all parameters were within normal limits and confirmed atrial pacing ...

The 73-year-old Prime Minister of Israel had a cardiac monitor places just about a week prior. That monitor showed signs of an atrioventricular block.

Cardiologist dies of heart attack at 41 despite normal ECG: What does death of Dr Gaurav Gandhi tell us? His ECG reading was normal. In about 20-30 per cent of cases, the first ECG may show up as ...

Additionally, the activation patterns resulting from RV pacing at different lead positions may result only in subtle morphological QRS differences making interpretation difficult and thus reducing the ...
