ECG findings are not diagnostic, but an abnormal ECG, especially showing previous myocardial infarction, left ventricular hypertrophy, left bundle branch block, or tachyarrhythmia (eg, rapid atrial fibrillation), increases suspicion for HF and may help identify the cause. An entirely normal...
ECG: An ECG is a recording of the activity of the heart. It shows the rate and rhythm of the heart and draws it out onto a strip for interpretation. Answer and Explanation:1 The easiest way to count heart rate on an ECG strip is to count the number of QRS complex present within a...
it is termed ectopic, meaning coming from somewhere other than the sinus node. The second ECG strip below shows an ectopic atrial rhythm. Note that the P wave is down in lead II and only up (not biphasic)
Heart Disease Testing: EKG (Electrocardiogram) Your heart's electrical activity can be seen with an EKG (also termed ECG or electrocardiogram). EKGs are tests that provide important information to the physician about the heart rhythm, damage to the heart, or a heart attack, and may provide se...
A simple way to diagnose a left bundle branch in an ECG with a widened QRS complex (> 120 ms) would be to look at lead V1. If the QRS complex is widened and downwardly deflected in lead V1, a left bundle branch block is present. If the QRS complex is wid...
(Goralnick, 2015). The ECG can also provide other information such as presence of bundle-branch block, left ventricle hypertrophy, and prior myocardial infraction (Floyd, 2016). The holter monitor is a portable ECG that is carried around and records 24 hours or more of heart activity to ...
Children with heart block have a higher ventricular rate than adults with acquired heart block; it is usually 45-60/min and may rise to 65-80/min on exercise. The pulse is of full volume because of the increased stroke output and, for the same reason, the heart is enlarged and the ...
This ECG, from a 70-year-old woman, is most consistent with which ONE of the following diagnoses? a. Sinus tachycardia with right bundle branch block (RBBB) b. Atrial flutter (2 : 1 AV conduction) with RBBB c. Monomorphic ventricular tachycardia ...
Ventricular tachycardia can occur with many variations of the QRS morphology, depending on where the arrhythmia originates, which sometimes makes diagnosis on ECG challenging. Below are two examples of ventricular tachycardia with different QRS morphologies — one with a right bundle branc...
