In Part 1 of our 2-part series on bradycardia and bradydysrhythmias we discussed a practical approach with electrophysiologist Paul Dorian and EM doc Tarlan Hedayati. How is the treatment of bradycardia different in the patient with hypothermia? In this, part 2, we discuss details of treatment. Cardiac ischemia? Myxedema coma?

Among them, bradycardia and pause detection could be erroneous during sleep as the heart rate may slow down significantly leading to potential inappropriate diagnosis. Insertable cardiac monitors (ICMs) are used widely for long term monitoring and diagnosis of various cardiac arrhythmia.

As the most common cause of syncope, vasovagal syncope (VVS) is the result of cerebral hypoperfusion caused by sudden-onset bradycardia and mediated by parasympathetic overdrive.1 1 VVS is generally categorized into three types: cardioinhibitory, vasodepressive and mixed type.
