What is an ECG or an EKG?Electrical Changes in the Cardiac Muscle Cells:As the cardiac impulse spreads over the cardiac muscle cells and causes the contractions, the electrical changes sweep over the cardiac chambers in a specific sequence. These electrical changes are also transmitted through the...
Following an abrupt change in heart rate (HR), QT adaptation is achieved within a delayed time frame. The exclusion of electrocardiograms (ECGs) showing rapid HR changes influences the level of a drug-induced QT prolongation. Continuous 12-lead ECG-Holter monitoring was performed in 31 healthy ...
Asystole (ay-sis-stuh-lee) is when there’s no electricity or movement in yourheart. That means you don’t have a heartbeat. It’s also known as flatline. That’s because doctors check the rhythm of your heart with a machine called an electrocardiogram -- also called an ECG orEKG. I...
At present you may run for cover on seeing an ECG. We hope to show you that there is no need to do this. If you experience a combination of confusion, apathy, and palpitations on hearing strange words, like ECG mapping, signal averaging, and QT dispersion by a consultant cardiologist on...
The first thing to know about ECGs is the waveforms. There is a P wave, the PR interval, and the QT interval which contains the QRS complex, the ST segment, and the T wave. There are a lot of variables to take into consideration when reading an ECG like current medications and ...
The optimal left ventricular ejection fraction (LVEF) to select patients early post myocardial infarction (MI) for risk stratification for prevention of sudden cardiac death (SCD) in the era of primary percutaneous coronary intervention (PPCI) is unknown.Consecutive patients (n = 1722) treated with...
This trial's primary end point is all-cause mortality (Brian Strom, MD, unpublished data, 2002). Quinolone antibiotics also pose a difficult dilemma. They are used on a wide scale for common infections without checking the ECG, an approach generally agreed on by the aforementioned LQTS experts...
Additional adverse effects include gastrointestinal side effects, transient liver function test elevations, and the risk of QT prolongation on ECG. Baseline assessments and regular monitoring are necessary to manage these side effects. While the response to Pasireotide may vary, it has shown better resu...
Answer to: How does the ECG vary and what is occurring during these conditions: junctional rhythm, second degree heart block and ventricular...
