The patient’s Day 2 ECG Summary continued to be viewed on the Mindray ViewStation. The total number of heartbeats was 138,622, including 13,157 premature ventricular contractions, accounting for 9%, and 237 short bursts of ventricular tachycardia. The patient’s condition...
Answer to: How does the ECG vary and what is occurring during these conditions: junctional rhythm, second degree heart block and ventricular...
How to use the 12-lead ECG to predict the site of origin of idiopathic ventricular arrhythmias童鸿
from Chapter 6 / Lesson 5 244K An electrocardiogram (ECG) records the flow of electrical current on three distinct waves. Explore the purpose of an ECG, the three wave types, and the purpose of each wave on an ECG. Related to this QuestionDescribe...
Mark out several consecutive R-R intervals on a piece of paper, then move them along the rhythm strip to check if the subsequent intervals are similar. Hint If you are suspicious ofatrioventricularblock(AV block), map out theatrialrateand theventricularrhythmseparately (i.e. mark the P waves...
OBJECTIVES: First, to assess the prevalence of ECG abnormalities in a cohort of elite Australian athletes using the 2010 ESC recommendations and determine how often group 2 ECG changes correlate with the evidence of significant cardiac pathology on further investigation. Second, to assess the impact ...
The limb leads record the ECG in the coronal plane, and so can be used to determine the electrical axis (which is usually measured only in the coronal plane). The limb leads are called leads I, II, III, AVR, AVL and AVF. Figure 2 shows the relat...
bundle branches, making its way to the Purkinje fibers and turning north again. This stimulates those Ventricular beefcakes to contract and deliver their payload to the lungs and body (if hearts had biceps, the left ventricle would be the proverbial “gun show”….it’s such a glory hog!)...

satisfactory level [26,28]. Therefore, the precise identification of the origin during the pre-ablation stage, while carefully examining the QRS morphology, is essential for a successful ablation. There are several diagnostic algorithms to determine the site of origin using the 12 lead ECG [29,...
