Torsade in a patient with left bundle branch block: is there a long QT? (And: Left Bundle Pacing).

Dr. Smith's ECG Blog

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

Transcutaneous Pacing: Part I

EMS 12-Lead

The receiving staff suspects pulmonary embolism due to S1Q3T3 on the ECG and administers TPA. The patient did have massive pulmonary emboli, but he also had profound intraventricular and subarachnoid hemorrhages. Learning points: TCP is primarily recommended for bradycardia that does not respond to atropine, or other agents.

This middle-aged patient presented with SOB, weakness, and mild pulmonary edema.

Dr. Smith's ECG Blog

This middle-aged patient presented with SOB, weakness, and mild pulmonary edema. There are 3 etiologies I always think of with bradycardia and AV block: 1. She previously had Atrial fibrillation with LBBB. Here is her ED ECG: Does this reveal the etiology of her symptoms? This shows atrial fibrillation. Hyperkalemia.

ECG Blog #396 — Why the Flat Line?

Ken Grauer, MD

KEY Point: Although true that patients with longstanding, severe pulmonary disease may manifest a QRST complex in standard lead I with marked overall reduction in QRST amplitude ( See ECG Blog #65 — regarding Schamroth’s Sign ) — you should never normally see a completely flat line in any of the standard limb leads.

Dip and plateau pattern of ventricular pressure tracing in constrictive pericarditis

All About Cardiovascular System and Disorders

The severe restriction causes elevation of pulmonary and systemic venous pressure which becomes equal to diastolic pressures in all cardiac chambers. Inspiratory fall in intrathoracic pressure is transmitted to the pulmonary veins, but not to the pericardial cavity. Relative change is more on the right sided chambers. Indian Heart J.

Q waves in association with RBBB are usually not seen in anterior leads unless there is pulmonary hypertension or anterior infarction. Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ). RBBB in blunt chest trauma seems to be indicative of several RV injury.

Assessment of LV Diastolic Function by Echo in SR and AF

All About Cardiovascular System and Disorders

Some of the other useful parameters are mitral E velocity deceleration time, changes in mitral inflow with Valsalva maneuver, mitral L velocity, isovolumic relaxation time, left atrial maximum volume index, pulmonary vein systolic/diastolic velocity ratio, color M-mode Vp and E/Vp ratio. Stage IV is considered as advanced.
