Bedside cardiac ultrasound showed moderately decreased LV function. Discontinue all negative chronotropic agents, since the risk of torsade is much higher with bradycardia or pauses. She was intubated. CT of the chest showed no pulmonary embolism but bibasilar infiltrates. The plan: 1. Place temporary pacemaker 3.

The ECG shows sinus bradycardia but is otherwise normal. On intravascular ultrasound (IVUS), the mid RCA plaque was described as "cratered, inflamed, and bulky," and the OM plaque was described as "bulky with evidence of inflammation and probably ulceration." The documentation does not describe any additional details of the history.

Her bedside cardiac ultrasound was normal We decided to cardiovert her since the time of onset was very recent. Baseline bradycardia in endurance athletes limits the use of ß-blockers. The Role of Sinus Arrhythmia: I found it interesting to compare the long lead II rhythm strips in the 3 serial tracings from today’s case ( Figure-1 ).

However, he suddenly developed a series of malignant ventricular arrhythmias. Below are printouts of some of the arrhythmias recorded. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation. The arrhythmia starts with a PVC having a short coupling interval.

There are three mechanisms of arrhythmia: automatic, re-entry, and triggered. The most common triggered arrhythmia is Torsades de Pointes. It is a benign arrhythmia which requires no specific treatment. Possible mechanisms of ventricular arrhythmias elicited by ischemia followed by reperfusion. Do not treat AIVR.

Bedside ultrasound showed no effusion and moderately decreased LV function, with B-lines of pulmonary edema. There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. malignant ventricular arrhythmias are present), rapid replacement of potassium is required.
