This ECG is a good example of an inferior wall M.I. that was confirmed and treated in the cath lab. The ST segments are elevated in Leads II, III, and aVF, but the amount of elevation may look subtle to some. When the amount of elevation seems small, what other signs can help us...
Background Automated detection of myocardial infarctions (MIs) in the RV and the posterior wall of LV are difficult in the standard 12-lead ECG. Addition of right-sided and posterior leads can improve detection sensitivity. This study shows the relationship between number of right and posterior ...
, resulting in an rsR′, qR, or M-shaped QRS pattern in V1. There are three mechanisms that can account for this pattern—normal variant; a gain of midtemporal anterior forces caused byRV enlargementor by concurrent LAF block; and a loss of posterior forces caused by aposterior wall MI...
The ablation strategy for persistent AF adds linear ablation of the mitral isthmus (MI) and electrical isolation of left atrial (LA) posterior wall (PW) using ablation index (AI)-guided high-power ablation (no fragmented potential ablation was performed at the index procedure) was not reported....

In conclusion, about 70% of patients with acute inferior MI also had involvement of right ventricle or posterior wall or both. Theprognosis appeared to be worse if there was RV卤 PW involvement. It may be worthwhile to perform 18-lead ECG routinely for patients with acute inferior MI.CHIU-...
