That said — the ECG in Figure-1 should prompt the following considerations: The symmetric chest lead T wave inversion in ECG #1 could be a sign of coronary disease, potentially with acute ischemia. See ECG Blog #313 — as well as My Comment at the bottom of the page in the June 17, 2024 post in Dr. Smith's ECG Blog ).

As discussed in ECG Blog #231 — Bidirectional VT is a special form of VT, in which there is beat-to-beat alternation of the QRS axis. Acute myocardial ischemia. See My Comment in the June 1, 2020 post in Dr. Smith's ECG Blog — for review of Pleomorphic VT. CPVT ( Catecholaminergic PolyMorphic VT ). Cardiac Sarcoidosis.

PEARL # 3: While not 100% predictive — seeing a significant negative component to the P wave in these leads ( as per the YELLOW arrows in Figure-2 ) — suggests that the V1,V2 electrodes may be placed 1 or 2 interspaces too high on the chest ( See ECG Blog #274 — for more on too high placement of the V1,V2 electrode leads ).

For full discussion of this case — See ECG Blog #392 — == The ECG in Figure-1 was obtained from a man in his 60s — who described the sudden onset of "chest tightness" that began 20 minutes earlier, but who now ( at the time this ECG was recorded ) — was no longer having symptoms.

For full discussion of this case — See ECG Blog #351 — == The ECG in Figure-1 — was obtained from a previously healthy older man who contacted EMS ( E mergency M edical S ervices ) because of "chest tightness" that began ~1 hour earlier.
