His bundle electrograms were obtained in 14 patients before and 30 minutes after the intravenous administration of reserpine. Nine patients received 1.0 mg of reserpine while 5 patients were given 0.5 mg. Reserpine did not alter the HQ or HS intervals. However, there were variable effects on the PA and AH intervals. These results can be explained by the interplay of two factors, norepinephrine release and a direct depressant action of the drug. Conduction through the AV node will be improved or delayed depending on which factor is dominant.

    Wolff-Parkinson-White syndrome (WPW) is an electrocardiographic diagnosis based on a short PR interval with the presence of a delta wave, but it can mimic a variety of electrocardiographic conditions. We present a 6 year old Saudi female whose WPW was easily mistaken as a left bundle branch...

    Transient asystole is seen relatively rarely by paramedics. It is often mistaken for syncope or seizures, which means that paramedics may miss an opportunity to help with a swift diagnosis and therefore help reduce morbidity and mortality (Deakin et al, 2010). This article explores the aetiology...
