Escitalopram-induced sinus bradycardia in coronary heart disease combined with depression: a case report and review of literature

Frontiers in Cardiovascular Medicine

Here, a rare repeated sinus bradycardia event due to escitalopram is first reported. In an 82-year-old female patient with cardiac dysfunction using digoxin, tachycardia (average heart rate of 93 beats/min) was demonstrated by electrocardiogram (ECG). heart rate was <60 beats/min.

Cardiomatics guide: Analyzing arrhythmias made easy

Cardiomatics

In a world where technology reigns supreme, one of the most profound tools in medicine remains the irreplaceable electrocardiogram (ECG). It can measure many aspects, from how fast the heart beats to how well its chambers conduct electrical energy. Sinus tachycardia – sinus rhythm above 100 bpm is a sinus tachycardia.

QT Correction Formulas Compared to The Rule of Thumb ("Half the RR")

In other words, if the QT is less than 1/2 the RR (QT non -prolonged) and the heart rate is above about 60 beats a minute, you can confidently say the QT is not prolonged. 3) At heart rates below 60, far more caution is due. 6) Use a different rule of thumb for bradycardia : Manually approximate both the QT and the RR interval.
