A 12-lead ECG showing atrial fibrillation at approximately 132 beats per minute Diagram of normal sinus rhythm as seen on ECG. In atrial fibrillation the P waves, which represent depolarization of the top of the heart, are absent. Diagnosis of atrial fibrillation is diagnosed on an electrocardiogram (ECG/EKG). The evaluation of atrial ...
This sinus rhythm is important because it ensures that the heart's atria reliably contract before the ventricles, ensuring as optimal stroke volume and cardiac output. [ 4 ] In junctional rhythm, however, the sinoatrial node does not control the heart's rhythm – this can happen in the case of a block in conduction somewhere along the pathway ...
On an electrocardiogram, or ECG, normally the “P wave” corresponds to the atrial contraction, which is followed shortly after by the “QRS complex”—which is the ventricular contraction. During AF, all these small areas are contracting at different times so you end up with this scribble sort of looking ECG, each little peak ...
Changes in the normal ECG pattern occur in numerous cardiac abnormalities, including: Cardiac rhythm disturbances, such as atrial fibrillation [6] and ventricular tachycardia; [7] Inadequate coronary artery blood flow, such as myocardial ischemia [8] and myocardial infarction; [9] and electrolyte disturbances, such as hypokalemia.

Normal variation causing LAD is an age-related physiologic change. Conduction defects such as left bundle branch block or left anterior fascicular block can cause LAD on the ECG. Pre-excitation syndrome as well as congenital heart diseases such as atrial septal defect, endocardial cushion defects can also cause LAD on ECG.
P-wave changes in left and right atrial hypertrophy. Bifid P waves (known as P mitrale) indicate left-atrial abnormality - e.g. dilatation [6] or hypertrophy. [1] If at least three different shaped P waves can be seen in a given ECG lead tracing, this implies that even if one of them arises from the SA node, at least two others are arising ...
Many studies from 2018 and on have found that magnesium status is inversely correlated with high blood pressure, stroke, coronary and ischemic heart disease, atrial fibrillation, heart failure ...
Since this accessory pacemaker also activates independently of the impulse generated at the SA node, two independent rhythms can be noted on the electrocardiogram (ECG). The P waves with a regular P-to-P interval (in other words, a sinus rhythm) represent the first rhythm. The QRS complexes with a regular R-to-R interval represent the second ...
