A single agent overdose causing AV blockade, QRS widening, and QT prolongation.... but reports of death only if QRS > 200ms. Which medication is this?
Fridericia Formula for calculating the QT interval on an (ECG) according to heart rate, described in 1920. Louis Sigurd Fridericia (1881-1947)
Bazett formula 'corrects' the measured QT interval to a value (QTc) attributable to a heart rate of 60 bpm. Thus providing a QT interval value that a particular patient would theoretically have if their heart rate was 60 beats/min
Drugs associated with QT Prolongation, QTc prolongation including Antipsychotics, antiarrhythmics, antidepressants, and antihistamines
QT interval is the time from the start of the Q wave to the end of the T wave, time taken for ventricular depolarisation and repolarisation
Louis Sigurd Fridericia (1881-1947) was a Danish physician. Eponymous term - Fridericia's formula: QT interval duration related to the cube root of the RR
