How do we figure out when bradycardia is due to a medical illness and when it is a primary cardiac problem? The post Ep 154: 4-Step Approach to Bradycardia and Bradydysrhythmias appeared first on Emergency Medicine Cases. What are some key ECG patterns that are sometimes missed by ED docs that can have devastating consequences?

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?

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.

For instance, if there were inappropriate sinus bradycardia at less than 60 bpm, the atrial pacer would take over if it is programmed to wait 1 second before firing. The atrial lead would pace if, after a programmed period of time, it did not sense an atrial beat (usually 1 second, corresponding to a rate of 60).
