Atrial Fibrillation Bradycardia Cardiac Arrest

While on telemetry monitoring he suffered cardiac arrest and was resuscitated. What ECG finding may have contributed to (or precipitated) the cardiac arrest? Note: The patient while on telemetry had alternating atrial fibrillation, sinus rhythm with 1st degree AV block and also periods of Wenckebach conduction.

Patient had an unwitnessed cardiac arrest without bystander CPR performed. Initial vitals show hypertension (175/85), Atrial Fibrillation with RVR as seen in Figure 1 , hypercapnia (99mmHg), and SPO2 of 100%. After 5 minutes post-ROSC, the atrial fibrillation converted to a sinus rhythm.

Written by Pendell Meyers First try to interpret this ECG with no clinical context: The ECG shows an irregularly irregular rhythm, therefore almost certainly atrial fibrillation. After an initially narrow QRS, there is a very large abnormal extra wave at the end of the QRS complex. Is there a long QT? How would you manage this patient?

Atrial Fibrillation Atrial fibrillation causes irregular heartbeat, and the heart's normal blood supply is affected. Since atrial fibrillation can also be intermittent, such patients should continuously monitor their heart activity while performing daily activities with a portable ECG device.

The rhythm now is atrial fibrillation. This patient is actively dying from a left main coronary artery OMI and cardiac arrest from VT/VF or PEA is imminent! Complete LMCA occlusion is associated with clinical shock and/or cardiac arrest. A repeat ECG was recorded about 15 minutes after the initial ECG.

Osborn waves have been reported with hypercalcemia, brain injury, subarachnoid hemorrhage, Brugada syndrome, cardiac arrest from VFib — and — severe, acute ischemia resulting in acute MI ( See My Comment in the November 22, 2019 post on Dr. Smith’s Blog ).

There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Torsades in acquired long QT is much more likely in bradycardia because the QT interval following a long pause is longer still. There is atrial fibrillation. If cardiac arrest from hypokalemia is imminent (i.e.,
