Family Medicine EOR: Cardiovascular (Smarty PANCE) Exam Questions and Answers 100% Verified and Updated 2024 Sinus tachycardia is a normal sinus rhythm but with a heart rate over ________ bpm 100 bpm Sinus bradycardia is a normal sinus rhythm with a rate of _________ bpm < 60 bpm EKG: no discrete P waves and an irregularly irregular pattern of QRS complexes. What's the dx? Atrial Fibrillation EKG: Regular, sawtooth pattern (F-waves), narrow QRS complex. What's the dx? Atrial Flutter EKG: PR interval > .2 seconds. What's the dx? First degree AV block EKG: Progressive *prolongation of the PR* interval culminating in a non-conducted P wave. What's the dx? Mobitz I Wenckebach block (longer, longer, drop now you've got a Wenckebach) EKG: Intermittent non-conducted P waves without progressive prolongation of the PR interval. What's the dx? Type II Mobitz block (some get dropped some get through now you've got Mobitz 2) EKG: there is complete absence of AV conduction - none of the supraventricular impulses are conducted to the ventricles. What's the dx? Third degree AV block (P's and Q's don't agree now you've got a 3rd degree) EKG: R and R' (upward bunny ears) in V4-V6. What's the dx? Left bundle branch block EKG: R and R' (upward bunny ears) in V1-V3. What's the dx? Right bundle branch block A faster-than-normal heart rate *beginning* above the heart's two lower chambers *in the atria*, *AV junction* or SA node. What's the dx? Supraventricular Tachycardia EKG: Shorter PR Interval, longer QRS complex and a delta wave - slurring slow rise of initial portion of the QRS. What's the dx? Wolff-Parkinson-White Syndrome EKG: Rapid irregular rhythm > 100 bpm. At least 3 distinct P-wave morphologies. What's the dx? Multifocal Atrial Tachycardia EKG: An abnormal (non-sinus) P wave is followed by a QRS complex. What's the dx? Premature Atrial Complex (PAC) EKG: Narrow QRS complex, either (1) without a preceding P wave or (2) preceded by an abnormal P wave with a PR interval of < 120 ms. What's the dx? Premature Junctional Complex (PJC) Broad QRS complex (≥ 120 ms) with abnormal morphology. What's the dx? Premature ventricular contractions (PVC) Every 3rd beat is a PVC Trigeminy Every other beat is a PVC Bigeminy EKG: Alternating bradycardia with paroxysmal tachycardia, often supraventricular in origin. What's the dx? Sinus Node Dysfunction (Sick Sinus Syndrome)Bradycardia-tachycardia syndrome EKG: Broad complex tachycardia originating in the ventricles. What's the dx? Ventricular Tachycardia (VT) EKG: Chaotic irregular deflections of varying amplitude No identifiable P waves, QRS complexes, or T waves. What's the dx? Ventricular Fibrillation EKG: Polymorphic ventricular tachycardia that appears to be twisting around a baseline. What's the dx? Torsades de Pointes (TdP
