The QT interval is the time from the beginning of the QRS complex, representing ventricular depolarization, to the end of the T wave, resulting from ventricular repolarization. The normal QT ...

BitMEX co-founder Arthur Hayes is fairly confident that Bitcoin’s drop to $77,000 marks the “bottom,” as quantitative ...

Whereas someone exhibiting marked prolongation of the QT interval with QTc exceeding 500 ms who was just externally defibrillated from torsades de pointes while swimming poses negligible diagnostic ...

Dr. George Shaker has huge hopes for a small radar device he developed with a team of researchers at the University of Waterloo. An engineer who has pursued the possibilities of radio waves for more ...

Patients with LQTS have impaired adaptation of the QT interval in response to changes in heart rate. A study by Dr Sami Viskin and colleagues has now shown that this maladaptation is exaggerated ...

called the QT interval, is longer than normal, which means there is a problem with the electrical system that controls the heartbeat. Hydroxyzine, in rare cases, may also cause a condition called ...

This new insight about the interrelation among PERED/weight, amplitude of ECG potentials, and durations of P waves, QRS complexes, and QTc intervals in patients with CHF can be immediately ...

Concomitant Class 1A (eg, quinidine, procainamide), or Class III (eg, dofetilide, amiodarone, sotalol) antiarrhythmics, or others known to prolong the QT interval: avoid.
