There are 6 different sinus arrhythmia. [1] [2]A normal heart should have a normal sinus rhythm, this rhythm can be identified by a ventricular rate of 60-100 bpm, at a regular rate, with a normal PR interval (0.12 to 0.20 second) and a normal QRS complex (0.12 second and less).
Anticoagulants: To prevent embolization.. Beta blockers: To block the effects of certain hormones on the heart to slow the heart rate.. Calcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles).
Rapid Interpretation of EKG's is a best-selling textbook for over 30 years [1] that teaches the basics of interpreting electrocardiograms. It adopts a simplistic fill-in-the-blank style [2] and is suited for medical students and junior residents. [1]
Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [5] using electrodes placed on the skin.
A cardiac electrophysiology study (EP test or EP study) is a minimally invasive procedure using catheters introduced through a vein or artery to record electrical activity from within the heart. [1]
Torsades de pointes – A type of ventricular tachycardia with a characteristic ECG appearance that can progress to ventricular fibrillation. Ventricular fibrillation (vfib) – Fibrillation of the ventricles is a life-threatening arrhythmia and should be treated by defibrillation and is a medical emergency. Vfib results from uncoordinated ...
The 2005 Joint European Resuscitation and Resuscitation Council (UK) guidelines [17] state that atropine is the first-line treatment especially if there were any adverse signs, namely: 1) heart rate < 40 bpm, 2) systolic blood pressure < 100 mm Hg, 3) signs of heart failure, and 4) ventricular arrhythmias requiring suppression. If these fail to ...
Both arrhythmias have at least 3 different P-wave morphologies in a single ECG lead, but the heart rate is different. When the heart rate is lower than 100 beats per minute, the heart rhythm is considered wandering atrial pacemaker. When the heart rate is greater than 100 beats per minute, the heart rhythm is considered multifocal atrial ...
