There is sinus bradycardia with one PVC. Additional research about MINOCA is needed to determine the efficacy of medications aimed at secondary prevention of AMI. She then had a 12-lead: What do you think? If there is any evidence of atherosclerosis, modifiable CAD risk factors should be treated aggressively. What is Type 2 MI?

Moreover, the research which appears to confirm this idea was indeed in relation to the circumflex, but they did not study Occlusion ; rather, they studied asymptomatic coronary disease. I am glad that Ken Grauer (below) brings up the issue of whether the presence of "T-wave in V1 taller than T-wave in V6" is evidence for OMI.

There’s sinus bradycardia, first degree AV block, normal axis, delayed R wave progression, and normal voltages. Hyperacute T waves are deflating, suggesting reperfusion but there is still reciprocal change in I/aVL and ST depression in V2, and the bradycardia is worse. Below is the ECG. What do you think? Take home 1.

The rule of thumb is less accurate, and the risk is higher because a long QT in the presence of bradycardia ("pause dependent" Torsades) predisposes to Torsades. 6) Use a different rule of thumb for bradycardia : Manually approximate both the QT and the RR interval. Other Research: According to this study b y Batchvarov et al. ,

Hypotension, bradycardia, kidney dysfunction and hyperkalaemia were the main causes of underprescription and/or underdosing, but up to a half of the patients did not receive target doses for unknown causes (51%, 41%, and 55% for BB, ACEi/ARB/ARNI and MRA, respectively).

To improve visualization — I've digitized the original ECG using PMcardio ) MY Thoughts on the ECG in Figure-1: This is a challenging tracing to interpret — because there is marked bradycardia with an irregular rhythm and a change in QRS morphology.

Patient 2 : 55 year old with 5 hours of chest pain radiating to the shoulder, with nausea and shortness of breath ECG: sinus bradycardia, normal conduction, normal axis, normal R wave progression, no hypertrophy.

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.
