Mianserin, maprotiline and intracardiac conduction.

Intracardiac Conduction Intervals in Children with Congenital Heart Disease

His bundle electrograms were recorded in 348 patients aged 2 months to 24 years following routine diagnostic cardiac catheterization. Among 41 children found to be free of anatomic or hemodynamic abnormality the following mean values were obtained: P-H interval, 93.4 ± 15.3 msec; P-A time, 21.2 ± 7.1 msec; A-H interval, 72.2 ± 15.9 msec; and H-V interval, 39.8 ± 5.2 msec. The remaining 307 pati...

A comparison in rabbit isolated hearts of the dysrhythmogenic potential of amitriptyline, maprotiline and mianserin in relation to their ability to block noradrenaline uptake.

1. In isolated hearts of rabbits, perfusion with (-)-noradrenaline (0.0059 to 5.9 micronM) resulted in chronotropic and inotropic responses and a shortening of the interval between peak atrial and peak ventricular tensions (the A-V contraction interval). No dysrhythmias developed but at higher concentrations (590 micronM) 2 out of 7 hearts developed dysrhythmias (extrasystoles). 2. Perfusion wi...

Mianserin and agranulocytosis.

An alcoholic woman who was admitted to hospital for detoxification was prescribed thyroxine because of hypothyroidism and mianserin to alleviate severe depression. After several weeks' treatment she became unwell and was readmitted to hospital. Haematological examination indicated agranulocytosis. Further extensive investigations elicited no cause for this other than the mianserin, since no suc...

Hepatic injury caused by mianserin.

Epileptiform seizures with maprotiline hydrochloride.

Two cases are described who developed epileptic seizures whilst taking maprotiline hydrochloride in therapeutic dosage. In both cases the electroencephalogram was normal and the fits stopped on withdrawal of the drug.
