Letters to the Editor 459

Sir,

We have read with great interest the case report1'1 which once more demonstrates that type I antiar-rhythmic drugs are to be preferred in the treatment of ectopic tachycardias; verapamil, on the other hand, may aggravate such arrhythmias.

To explain the arrhythmogenic effect of verapa-mil, the authors hypothesize that this was mediated through the haemodynamic effect of the drug, namely hypotension. We would doubt that this is the mechanism. Indeed, studying the effect of verapamil in children after open heart surgery (Am J Cardiol 1987; 60: 692), we have recently

demon-strated the emergence of ectopic pacemakers as a direct effect of verapamil. In the case of Wren etal., the exacerbation of an ectopic pacemaker is the probable mechanism.
