Sleep Medications Containing Melatonin can Potentially Induce Ventricular Arrhythmias in Structurally Normal Hearts: A 2-Patient Report. Erasmus Medical Centre, Department of Cardiology, Electrophysiology, Rotterdam, the Netherlands.
Can melatonin cause rapid heart rate?
The evening administration of melatonin induced an increase of blood pressure and heart rate throughout the 24 h period (ΔSBP = + 6.5 mmHg, P < 0.001; ΔDBP = + 4.9 mmHg, P < 0.01; ΔHR = + 3.9 beats min−1, P < 0.01). The DBP as well as the HR increase were particularly evident during the morning and the afternoon hours.
