The ECG showed sinus bradycardia with striking early repolarization, ST segment elevation, and peaked T waves. These ECG abnormalities represent an unusual pattern for beta-adrenergic blocking agent toxicity.Grant R GwinupAnnals of Emergency Medicine...
The ventricular rate can be calculated by using the frequency of the QRS complexes, which correlate with ventricular systoles. The atrial rate, which correlates with atrial systole, can be calculated by using the frequency of the P waves (e.g., when assessing supraventricular arrhythmias). In...
De Winter’s T-waves: Precordial leads: V1-V5 Upsloping ST depression >1 mm Tall/peaked T waves Associated with proximal LAD occlusion Great article on T-wave inversion: click here Posterior MI: ST depression >0.5 mm in leads V1-V3 with upright T waves May develop tall R waves in ...
In some cases there can be a notched (or bifid) p-wave known as “p mitrale”, indicative of left atrial hypertrophy which may be caused by mitral stenosis. There may be tall peaked p-waves. This is called “p-pulmonale” and is indicative of right atrial hypertrophy often secondary to...
The P waves are abnormal, and they are tall, narrow, and peaked inleads II, aVF, and V1-V2. The P-wave morphology is characteristic ofaP pulmonale, a result ofright atrial hypertrophy. This may also betermed ari...
Tall peaked T waves which are often seen in the earliest stage of an evolving transmural infarct, may also be occasionally encountered during stress testing and indicate severe inducible ischemia.2 We describe a patient who demonstrated these ECG signs in the precordial leads....
(STD), T wave abnormal (TAb), peaked T waves (PT), elevated U wave (EU), Brugada Syndrome (BS), sinus tachycardia (ST), sinus bradycardia (SB), significant sinus bradycardia (SSB), sinus arrhythmia (SA), premature atrial contraction (PAC), atrial bigeminy (AB), atrial premature beat ...
U wave, which is a position deflection after the T wave Tall peaked T waves Widening of the QRS complex and increased amplitude Answer:(b) 21. ECG identified by the PR interval tends to become longer with every succeeding ECG complex until there is a P wave not followed by a QRS is ob...
* No pathological ST segment elevations, depressions, or Q waves. * Frontal plane axis is normal. Slightly early R wave transition in the precordial leads. * No ectopic beats or pauses. It is very important for students to become familiar with normal ECG characteristics before they learn abnor...
Hypokalemia causes U waves in the ECG seen as a positive wave just after the T wave. Hyperkalemia causes peaked T waves initially, then an intraventricular conduction delay with a widened QRS complex, then bradycardia. Eventually a “sine wave” pattern ensues. ...
