The researchers were able to show that those who had been ill with COVID-19 could also suffer from heart rhythm disturbances, both in the form of so-called tachycardias , when the heart ha rate is high, and bradyarrhythmias , when the heart is slow so that a pacemaker is sometimes needed.

M BBB is a special type of IVCD that although uncommon, is important to recognize because it identifies a group of patients with: i ) Very severe underlying heart disease; ii ) A much higher predisposition for developing complete AV block ( and needing a pacemaker ); and , iii ) An extremely poor longterm prognosis.

As ATTR-CM is associated with conduction disease, we sought to determine its prevalence in patients with idiopathic high-degree atrioventricular (AV) block requiring permanent pacemaker (PPM) implantation. Demographics, comorbidities, electrocardiographic and imaging data from the time of device implantation were retrospectively collected.

Asynchronous pacing seems like the safe setting, EXCEPT that it means that the pacemaker can trigger on the T-wave, which can result in Ventricular Fibrillation. Our electrophysiologists give an example of this here: "Asynchronous" mode means that the pacemaker will pace regardless of what the native beats are doing.

Is a pacemaker needed? As a result — IF no "fixable" cause is found ( ie, ischemia/infarction — electrolyte disturbance — rate-slowing medication ) — then because of the AV block and very slow heart rate, this patient will probably need a pacemaker. QUESTIONS: HOW would you interpret the rhythm in Figure-1 ?

My Immediate Impression — was that this elderly woman with a several week history of symptoms would most likely leave the hospital with a pacemaker. Given this patient's older age — if nothing "fixable" is found, she most likely has SSS ( S ick S inus S yndrome ) and will need a pacemaker ( See ECG Blog #342 for more on SSS ).

If there had been — a temporary atrial pacemaker could have been considered as a way of increasing the heart rate to suppress a bradycardia-dependent arrhythmia ("overdrive pacing"). Some residual ischemia in the infarct border might still be present. QUESTION: How will you handle this arrhythmia given the clinical scenario?

My thoughts were the following: ECGs #1 and #2 showed a completely unreliable sinus pacemaker, with presumed high-grade 2nd-degree AV block — and frequent resultant pauses of over 2 seconds ( that would have been even longer had it not been for intermittent relief from the atrial escape focus ). What Does this All Mean?

If the block is not vagal in nature, the patient should receive a pacemaker. There was a randomized trial to determine whether pacemakers could benefit patients with vasovagal syncope, aptly named The North American Vasovagal Pacemaker Study (VPS). In the repeat study (VPS II), EVERY patient had an implanted pacemaker.
