Introduction The incidence of arrhythmia in heart failure with non-reduced ejection fraction (HFnon-rEF) in patients who have a history of hospitalisation is unclear.

I’d guess the overall rhythm is sinus, perhaps with a wandering atrial pacemaker and very frequent ventricular ectopy with multiple couplets. I suspect BEST treatment for these rhythm disturbances is correction of this patient’s underlying heart disease — but that of course is easier said than done …. Beats #3 and 6 look like PVCs.

I will leave more detailed rhythm discussion to the illustrious Dr. Ken Grauer below, but this use of calipers shows that the rhythm interpretation is: Sinus bradycardia with a competing (most likely junctional) rhythm. Neverthelss, his anterior wall was saved and he had normal ejection fraction without heart failure.

In selected patients with discrete proximal LBBB the pacemaker stimuli may breakthrough the block. Unfortunately ,there appears to be a herd mentality, gradually creeping in to many of us, to jump over from traditional RV /RA pacing to the bundle branch area pacing , as an alternative to CRT or even regular bradycardia pacing.

There are 3 etiologies I always think of with bradycardia and AV block: 1. She had a permanent pacemaker implanted. After pacer AND conversion to sinus rhythm: Computer diagnosis: IMPRESSION ELECTRONIC VENTRICULAR PACEMAKER ABNORMAL RHYTHM ECG What is missing from this interpretation? Hyperkalemia. Her K was normal 3.

The patient care narrative states no further changes in heart rate with persistent LBBB morphology. He received a permanent pacemaker during the subsequent inpatient stay. LBBB may be the precipitating cause of the heart failure syndrome, or may portend high mortality when identified in preexisting heart failure.

Here are inferior leads, and aVL, magnified: A closer inspection of the inferior leads and aVL Sinus bradycardia. A right heart cath revealed increased right heart pressures and a similarly timed echo revealed mild right heart failure. I had no history on the case and no prior ECG for comparison. What do you think?

Baseline bradycardia in endurance athletes limits the use of ß-blockers. While possible that this represents underlying complete AV block with Wenckebach conduction out of a junctional escape pacemaker — the frequency of this unusual arrhythmia has greatly decreased in recent years with reduced use of Digoxin.

PVCs N ot generally considered abnormal ECG findings: Isolated PAC, First Degree AV Block, Sinus bradycardia at a rate of 35-45, and Nonspecific ST-T abnormalities (even if different from a previous ECG). Thus, if there is documented sinus bradycardia, and no suspicion of high grade AV block, at the time of the syncope, this is very useful.

Within ten minutes, she developed bradycardia, hypotension, and ST changes on monitor. Bradycardia and heart block are very common in RCA OMI. 2:34 PM, following right heart catheterization She then went into atrial fibrillation with complete heart block and junctional escape rhythm prompting placement of transvenous pacemaker.
