2nd degree AV block type 1 ekg finding - PR interval gradually lengthened until there is a dropped QRS 3rd degree AV block - SA and AV node are not communicating. Causes hypotension. This is a complete heart block SA and AV node are firing independently of each other - no association between atria and ventricle - R waves regular because AV node firing regularly - P waves regular because SA node is firing regularly 3rd degree AV block EKG finding - QRS complex will be wide and there will b...
