In which type of heart block do none of the atrial impulses reach the ventricles? ◦ A) First-degree AV block ◦ B) Second-degree AV block type I ◦ C) Second-degree AV block type II ◦ D) Third-degree AV block D) Third-degree AV block (3rd degree doesn't reach ventricules...
Hello, folks. I have felt some strange sensations with my heart. It seemed like it worked irregularly. I went to a doctor and he ordered an EKG.
The electrocardiogram is a recording of the electrical activity of the heart as it undergoes excitation (depolarization) and recovery (polarization) to initiate each beat of the heart. This electrical activity is represented by a tracing showing the various phases of the activity above or below ...
When the heart muscle contracts and relaxes, a small electrical current is generated. An electrocardiogram (ECG or EKG) is a painless, non invasive test that uses electrodes on the skin to measure these small electrical changes and produces a graph showing the electrical changes over a period ...
1st Degree Heart Block. 62 year old female patient with COPD monitored during aorto-bifemoral graft procedure.
Sometimes aortic abscesses can present as PR interval lengthening or heart block due to the extension of infection. We present an atypical presentation of aortic root abscess with chest pain and ischemic EKG changes. A 45-year-old intravenous drug user presented with chest pain episodes with EKG...
How does the ECG vary and what is occurring during these conditions: junctional rhythm, second degree heart block and ventricular fibrillation? Explain the events that are occurring in the heart during each phase of an EKG (PQRST) and explain why a person can have a...

Also included is the Normal Detector, which indicates whether your heart rate and rhythm are normal, and the Unreadable Detector, which tells you when to retake an EKG so physicians receive only the highest quality recordings. The collected recordings are stored and can be viewed in the iPhone...
