Acute: sudden severe pain [1] Chronic: abdominal pain after eating, unintentional weight loss, vomiting [2] [1] Usual onset > 60 years old [3] Types: Acute, chronic [1] Risk factors: Atrial fibrillation, heart failure, chronic kidney failure, being prone to forming blood clots, previous myocardial infarction [2] Diagnostic method: Angiography ...
Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. [ 11 ] [ 12 ] It often begins as short periods of abnormal beating , which become longer or continuous over time. [ 4 ]
Individuals with right atrial isomerism develop two sinoatrial nodes, as they have 2 mirrored right atria, whereas those with left atrial isomerism fail to develop a sinus node at all. Thus, patients with left atrial isomerism are more likely to experience atrial fibrillation , or irregular rapid heart beat, and abnormal heart rhythm, known as ...
Rhythm interpretation is an important part of healthcare in Emergency Medical Services . Trained medical personnel can determine different treatment options based on the cardiac rhythm of a patient. There are many common heart rhythms that are part of a few different categories, sinus arrhythmia, atrial arrhythmia, ventricular arrhythmia.
A sinus rhythm is any cardiac rhythm in which depolarisation of the cardiac muscle begins at the sinus node. [1] It is necessary, but not sufficient, for normal electrical activity within the heart. [2] On the electrocardiogram (ECG), a sinus rhythm is characterised by the presence of P waves that are normal in morphology. [2]
normal sinus rhythm) to reverse the cardiomyopathy. [5] [9] The treatment of the tachyarrhythmia depends on the specific arrhythmia, but possible treatment modalities include rate control, rhythm control with antiarrhythmic agents and cardioversion, radiofrequency (RF) catheter ablation, or AV node ablation with permanent pacemaker implantation ...
If the rhythm is irregular, it is usually due to conduction of an irregular rhythm that originates in the atria, such as atrial fibrillation. In the picture, an example of torsades de pointes can be seen; this represents a form of irregular ventricular tachycardia. In this case, the ICD will rely on rate, not regularity, to make the correct ...
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 ...
