Rhythm:Both the atrial and ventricular rhythms are regular but dissociated. PR Interval:There is no observable relationship between the P-waves and R-waves. P-waves:Typical in size and shape. Clinical Manifestations Often occurs secondary to sinus bradycardia. ...
HR = 150/RR interval in cm (e.g., if there are 2 cm in between two consecutive R waves, HR = 150/2 = 75/min) HR = 60/RR interval in seconds (e.g., if there is a 0.5 s interval between two successive R waves, HR = 60/0.5 = 120/min) Irregular QRS rhythm: HR = 6...

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. Hyperacute T waves are large and...

What is this rhythm called? There are no P waves present, and no flutter or fibrillation waves can be seen. There are 2 possibilities: 1. There is a sinus arrest with a junctional escape rhythm. The junctional rhythm either cannot conduct retrograde to the atria (therefore no inverted retrog...
(↔), indicating a first-degreeAV blockor prolonged AV conduction. Using this PR interval, it can be seen that the notches on the T waves (v) are indeed P waves, as they are associated with the same PR interval (↔). Therefore, there is a normal sinus rhythm with prolonged AV ...
Irregularly irregular rhythm No P waves Absence of an isoelectric baseline Variable ventricular rate QRS complexes usually < 120ms, unless pre-existing bundle branch block, accessory pathway, or rate-related aberrant conduction Fibrillatory waves may be present and can be either fine (amplitude < ...
Heart sounds are normal, irregular rhythm and bradycardia noted. No edema noted in extremities. Patient skin is cool to touch, slightly clammy. EEG shows prolonged QRS wave, with ischemic ST changes and PVCs. Chest radiograph clear. 1027 Words 5 Pages Better Essays Read More Left Fallopian ...
People with AF usually have a significantly increased risk of stroke. Clinically, AF is diagnosed by a surface electrocardiogram (ECG). AF is characterized by the absence of P-waves and by a rapid irregular ventricular rhythm. The algorithms for automatic detection of AF either rely on the ...
