ECG Wave Pattern Strip for Ventricular Fibrillation ECG (electrocardiogram or EKG) of VFib shows only fast irregular electrical tracings with no tracings showing a QRS (the large “spike” pattern on a normal ECG) indicative of a heartbeat (ventricular contraction). Subscribe to MedicineNet's He...
Atrial fibrillation is an irregular heart rate that is not itself life-threatening but can lead to stroke. Reviewed by a board-certified cardiologist.
The top image shows a normal ECG wave strip pattern, while the bottom image shows an EKG of a patient with rapid atrial fibrillation with large peaks that are irregular. What drugs are used to treat and manage atrial fibrillation? This article will introduce you to treatments for AFib. Other...
Atrial fibrillation (Afib) and ventricular fibrillation (Vfib) are both a type of abnormal heart rhythm (arrhythmia). Atrial fibrillation is caused by irregular electrical impulses in the atria and ventricular fibrillation is caused by irregular electric
T Wave InversionBackground: Atrial fibrillation (AF) and T wave inversion (TWI) are occasionally found on pre-operative electrocardiograms (EKG) of patients with long standing hy-pertension (HTN) associated with left ventricular hypertrophy (LVH). Each of these two pathologies, AF and LVH, can...
Maybe you didn’t sleep well last night, or your allergies are acting up. Even a little bit of extra weight can have you huffing and puffing after going up the stairs. However, another underlying issue could be atrial fibrillation, or AFib. But what is atrial fibrillation?
Atrial fibrillation(AForA-fib) is the most common cardiac arrhythmia (irregular heart beat). It may cause no symptoms, but it is often associated with palpitations, fainting, chest pain, or congestive heart failure. AF increases the risk of stroke; the degree of stroke risk can be up to se...
What is atrial fibrillation (A-fib)?A-fib is an irregular heartbeat that reduces your heart's ability to pump blood through your body. A-fib may come and go, or it may be a long-term condition. A-fib can cause life-threatening blood clots, stroke, or heart failure. It is important...
Electrocardiogram (ECG or EKG):This is the primary test to determine when an arrhythmia is atrial fibrillation. The ECG can help the doctor distinguish AFib from other arrhythmias that may have similar symptoms (atrial flutter, ventricular tachycardia, or runs of ventricular tachycardia). The test ...
The fibrillation is maintained by re-entry circuits formed by some of the wavelets. This process is potentiated in the presence of a dilated LA — the larger surface area facilitates continuous waveform propagation.Left: Focal activation originating from pulmonary vasculatureRight: Multiple small ...
