The following are key points to remember from a review article on cardiac implantable electronic devices (CIEDs), which include pacemakers for bradycardia, biventricular pacemakers for heart failure, and implantable cardioverter–defibrillators (ICDs) for the treatment of sudden cardiac death:

Introduction: Leadless pacemakers (LP) are increasingly utilized in pts with bradycardia and may be associated with better outcomes compared to right ventricular pacing (RVP). Conduction system pacing (CSP) with HBP or LBBAP have been associated with reduction in death or heart failure hospitalization (HFH).

Conduction system pacing (CSP), including both left bundle branch area pacing (LBBAP) and His-bundle pacing (HBP) has been proposed as an alternative therapy option for patients with indication for cardiac pacing to treat bradycardia or heart failure.

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. The primary endpoint is new-onset 6 min or more persistent AF detected by ILR.

Some of the leads are not labeled — and I don’t know if any 2 make up a complete ECG — but clinically, that really isn’t important since your patient has heart failure from cardiomyopathy and NOT and acute infarction. There definitel are periods of bradycardia (so pacing may be needed for that). Beats #3 and 6 look like PVCs.

Our collaboration with Orchestra BioMed will explore how cardiac pacing can go beyond management of bradycardia and conduction disease to treat hypertension as well,” said Robert C. This leaves a gap in the care of these patients and increases their risk for heart attack, stroke and heart failure progression. Kowal, M.D.,

During the night, while on telemetry, the patient became bradycardic, with periods of isorhythmic AV dissociation (nodal escape rhythm alternating with sinus bradycardia), and there were sporadic PVCs. NT-pro-BNP peaked at 4831, consistent with heart failure. This is what T-waves look like when there is a long QT."

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.

plaque disruption), the T waves still manifest markings of a previous state of suboptimal coronary flow that resolved: Type II supply-demand mismatch in the setting of extreme bradycardia. LBBB may be the precipitating cause of the heart failure syndrome, or may portend high mortality when identified in preexisting heart failure.

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 is less compelling academic reasons for this change, than we think.

And, after the shock, if there is bradycardia, it can be covered by these two pacing electrodes, one at the tip, and one proximal to it. So, after myocardial infarction, the risk is more of heart failure, than arrhythmic death. These are high voltage, defibrillator shock coils. That is one reason.

There are 3 etiologies I always think of with bradycardia and AV block: 1. While the diagnosis of SSS may become readily apparent early on in many patients clear indication for pacing usually does not become established until there is profound, symptomatic bradycardia usually requiring pauses of at least 3.0 Hyperkalemia.

Use of drugs producing bradycardia like beta blockers in stages III and IV may precipitate low output state. One situation is decompensated advanced systolic heart failure with large left ventricle. In stage IV, this restrictive filling pattern remains fixed even during Valsalva maneuver. Stage IV is considered as advanced.

There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Torsades in acquired long QT is much more likely in bradycardia because the QT interval following a long pause is longer still. Heart failure leading to death was related to all subclasses of PVC.

Baseline bradycardia in endurance athletes limits the use of ß-blockers.

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.
