Finally, do a coronary angiogram Possible alternative to pacing is to give a beta-1 agonist to increase heart rate. For more on Torsades de Pointes vs PMVT See My Comment in the October 18, 2023 post and the September 2, 2024 post in Dr. Smith's ECG Blog ). Discontinue all QT proloning medications, including azithromycin 6.

Circulation

Circulation, Volume 150, Issue Suppl_1 , Page A4142716-A4142716, November 12, 2024. Background:Heavily calcified coronary bifurcation lesions present significant challenges during percutaneous coronary intervention, particularly during atherectomy due to the risk of side branch occlusion from plaque shift.

What would you do with acute chest pain and this ECG? You might see what the Queen thinks.

The patient was taken emergently to the cath lab for a pericardiocentesis instead of a coronary angiogram. in My Comment in the January 13, 2024 post in Dr. Smith's ECG Blog — in which I review the importance of considering filter settings when assessing if the rhythm in a given ECG is or is not paced? ).

How a pause can cause cardiac arrest

Dr. Smith's ECG Blog

A coronary angiogram was done that did not show significant coronary artery disease. Had there been recurrent episodes of pause-dependent TdP, temporary ventricular pacing at a higher heart rate would have been indicated to suppress the pauses and in that way decreasing the risk of further episodes of TdP.
