Abstract:
Vagal maneuvers are techniques used to increase parasympathetic tone, particularly useful in the management of hemodynamically stable supraventricular tachycardias. If ineffective, adenosine can be attempted. We present a patient with atrioventricular nodal re-entrant tachycardia (AVNRT), who could not effectively perform Valsalva maneuvers and had contraindications for carotid massage and adenosine administration, that converted into sinus rhythm by using a rectal thermometer. This maneuver was reproduced on various occasions. We suggest that rectal vagal maneuver may provide an additional therapeutic modality for selected patients with AVNRT.

01:13Equipments Used to Measure Body Temperature
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...
