A fascinating electrophysiology case. What is this wide complex tachycardia, and how best to manage it?

Dr. Smith's ECG Blog

The ECG was interpreted as showing atrial flutter with 2:1 conduction. Are you confident there is no ischemia? The heart rate is about 130 bpm. The heart rate could be compatible with that of a 2:1 conducted atrial flutter. Also, lead I could give the initial impression of showing flutter waves.

Ischemic ST depression maximal in V1-V4 (vs. V5-V6), even if less than 0.1 millivolt, is specific for Occlusion Myocardial Infarction (vs. subendocardial non-occlusive ischemia)

Dr. Smith's ECG Blog

The patient has heart failure as a result of this event. If this STD were due to LVH or to subendocardial ischemia, rather than posterior OMI, it would be maximal in V5 and V6. 2 months later, he presented in pulmonary edema with atrial flutter and formal echo had EF 20% Why did this happen? Alcohol intoxication?

What does the ECG show in this patient with chest pain, hypotension, dyspnea, and hypoxemia?

Dr. Smith's ECG Blog

The rhythm is 2:1 atrial flutter. The flutter waves can conceal or mimic ischemic repolarization findings, but here I don't see any obvious findings of OMI or subendocardial ischemia. The bedside echo showed a large RV (Does this mean there is a pulmonary embolism as the etiology?) Lots of info here.

New Onset Heart Failure and Frequent Prolonged SVT. What is it? Management?

Dr. Smith's ECG Blog

There is no evidence of infarction or ischemia. NT-proBNP values less than 300 pg/ml have a 99% negative predictive value for excluding congestive heart failure. A cutoff of 1200 pg/ml for patients with a normal eGFR is very specific for heart failure. The other atrial flutter types are: 1.

Evidence of acute ischemia (may be subtle) vii. History of Cardiovascular disease (all studies): Especially any history of heart failure or structural cardiac disease, including valvular 4. to 22.7), a history of congestive heart failure (OR: 5.3, 2nd or 3rd degree AV blocks or sinus pause of at least 2 seconds iv.
