Here is the first ED ECG: COMPUTER INTERPRETATION: Electronic Atrial Pacemaker. He has a h/o 3rd degree heart block and has a pacemaker. His pacemaker was interrogated and it was found that the pacemaker was not adquately capturing. An elderly patient had a fall from probable syncope, and could not get up. The K was 5.8
milla1cf Fri, 01/05/2024 - 11:42 June 5, 2024 — Medtronic , a global leader in healthcare technology, today announced it has received CE (Conformité Européenne) Mark for its Micra AV2 and Micra VR2 , the next generation of its industry-leading miniature, leadless pacemakers. Launching the first pacemaker for use in MRIs in 2011.
Methods We conducted a retrospective observational study including 1691 consecutive patients implanted with an active fixation pacing and defibrillator lead at our institution between January 2015 and January 2021. Results Univariate and multivariate analyses were used to identify predictors of RV perforation.
The Beginning: The Need for Cardiac Remote Patient Monitoring The first implantable pacemaker, was developed in the late 1950s, but the first clinically successful pacemaker was implanted into a 77-year-old at a Veterans Affairs hospital in New York in 1960.
Patients with SP or AVB, 21 years of age or younger, who underwent CNA between 2015 and 2021 were included. Conclusion CNA may be an effective alternative to pacemaker implantation in pediatric patients with syncope or significant symptoms secondary to functional SP or AVB. Methods This is a single-center, case series study.
The Heart Rhythm Society recently unveiled the new 2023 HRS/EHRA/APHRS/LAHRS Expert Consensus Statement on Practical Management of the Remote Device Clinic , marking significant progress since the previous 2015 version, which originally identified remote monitoring as the standard of care for implantable cardiac device clinics.
Edits by Meyers and Smith A man in his 70s with PMH of hypertension, hyperlipidemia, type 2 diabetes, CVA, dual-chamber Medtronic pacemaker, presented to the ED for evaluation of acute chest pain. American Heart Journal 170(6):1255-1264; December 2015. Sent by Pete McKenna M.D. Triage ECG: What do you think? I cannot be anything else.
Figure-1: Illustration of the Emery Phenomenon ( adapted from My Comment in the February 23, 2023 post in Dr. Smith's ECG Blog — and — from the 2015 post by Dr. Bojana Uzelac on Armel Carmona’s ECG Rhythms website ). Meyers alludes to in his excellent discussion. The 2 sets of limb leads shown are from this Feb.
NOTE #3: For review of the "many faces" of benign ST-T wave variants — numerous examples are shown and discussed in the March 22, 2022 post by Dr. Meyers — and earlier, in the January 7, 2015 post in Dr. Smith's Blog. This gradual change in P wave morphology as the heart rate varies could be consistent with a wandering atrial pacemaker.
Though sinus bradycardia is usual, other abnormalities like sinus arrhythmia, sinus arrest, wandering atrial pacemaker and coronary sinus rhythm have been described. 2015 Apr;16(4):353. Athlete’s bradycardia due to increased parasympathetic tone and decreased sympathetic tone is a well-known observation.

Figure-1: The initial ECG in today's case ( = ECG #1 , on the BOTTOM ) — compared to the repeat ECG after the patient did squats in the room ( = ECG #2 , on the TOP ).
Negative predictors of adverse outcome: Pacemaker Pre-syncope or "near-syncope," but there is still some small risk (5, 18) These last two are identified in studies, but I consider them dangerous signs and symptoms in their own right, as above: 10.
