A 76-year-old woman with known ischemic cardiomyopathy, a left ventricular ejection fraction of 25%, and a previously inserted pacemaker presents to her cardiologist concerned that there is a problem ...
The rhythm is regular at a rate of 120 beats/min. A pacemaker stimulus occurs before each QRS complex (→). This is ventricular pacing. Because the pacing rate is 120 beats/min, the mode of pacing must ...
Wandering atrial pacemaker is similar to multifocal atrial tachycardia except the heart rate is normal ― that is, less than 100 beats per minute. Wandering atrial pacemaker occurs when multiple areas ...
If you are a nurse, doctor or other medical professional that deals with cardiac issues or ECG readings, you owe it to yourself and your patients to take an EKG interpretation course. An EKG ...
This ECG shows ventricular pacing. Note the pacer spike prior to each QRS complex, most apparent in leads V5 and V6. The P waves appear sinus in origin and have no association with the QRS complexes ...
A specialist tells how to interpret subtle changes on the ECG, including those caused by two life-threatening syndromes you might otherwise miss. Reading ECGs is like learning to appreciate art—it is ...
The following text summarizes information provided in the video. The uses of electrocardiographic (ECG) monitoring have evolved from the tracking of heart rate and basic rhythm to the detection of ...
The cardiac pacemaker harmlessly dissolves over the course of 35 days. (Courtesy: Northwestern University) Temporary cardiac pacemakers provide essential pacing for patients with short-term heart ...
In the normal heart, the lower chambers (ventricles) pump at the same time and in sync with the heart's upper chambers (atria). Cardiac resynchronization therapy (CRT), also called biventricular ...
