A 76-year-old woman presents with a persistently rapid heart rate that she attributes to her pacemaker. What does the ECG ...

Fourteen studies and two case series were found describing ST-segment abnormalities and/or significant Q-waves in association ... a peak of 120.1 ± 15.6 bpm (p < 0.001) – a response that ...

An electronic circuit capable of integrating the electrocardiogram is described. The net areas of the QRS complex, the T wave and of the entire ventricular complex ...

Elevated p-eIF2α, and its proper sensing by the decameric eIF2B complex, are essential to balance translation. Knockdown or mutation of eIF2Bα and eIF2Bδ, two eIF2B subunits responsible for sensing ...

This case illustrates a toxic effect of flecainide in widening the QRS complex and inducing repolarisation abnormalities on exercise testing in a 67 year old woman, who had presented breathless in ...

ECG revealed CHB with narrow QRS complexes (figure 1). No other organic cardiac problem was detected in echocardiography. She was put on orciprenaline 10 mg two times per day. Apart from fatigue, ...
