Introduction Extrasystole, or premature ventricular extrasystole (PVC), is caused by an ectopic pacemaker in the ventricles. They appear as wide QRS complexes, not preceded by P waves. The typical pattern for these PVCs is a tall R wave, with inverted T waves with LBBB or RBBB morphology. These are usually…
Introduction Medical billing is an integral part of any healthcare practice. Proper and timely billing ensures cash flow and limits claim denials. Most healthcare providers have traditionally done in-house medical billing because they believed it gave them better control and cost savings. However, beneath the surface, in-house billing can come…
Introduction Heart block, also known as atrioventricular (AV) block, refers to a delay or disruption in the conduction of electrical impulses from the AV node to the ventricles. Understanding the AV Node The AV node is a specialized conduction point that transmits electrical impulses from the atria to the ventricles,…
Introduction Cardiac markers play a crucial role as diagnostic and prognostic tools in cases of acute coronary syndrome (ACS) and central chest pain. These markers are released into the bloodstream when heart muscle tissue is either damaged or subjected to significant stress. Cardiac markers are classified into the following categories: …
Introduction An ECG (electrocardiogram) is a diagnostic tool that records the electrical activity of the heart. It is often considered the gold standard for identifying normal or abnormal heart function. Understanding the waves and what they represent is the first step in mastering ECG interpretation. Each wave provides information about…
Introduction Acute coronary syndrome is a spectrum of urgent cardiac diseases that include unstable angina, non-ST-segment elevation myocardial infarction (NSTEMI), and ST-segment elevation myocardial infarction (STEMI). Rapid recognition and treatment in an emergency situation are of the utmost importance for improved patient outcomes and the elimination of complications that, for…
Introduction ECG, which means electrocardiogram, is a simple way to see and capture the heart’s electrical activity on paper. In this article, we’re gonna talk about how to perform an ECG. How to record and ECG The ECG machine uses electrodes that are stuck on the chest and limbs. These…
Introduction Palpitations are feeling your heart race or flutter out of nowhere, and it can be unnerving. It may make you think, “Is something wrong with me?” The truth is, palpitations are usually harmless. They’re surprisingly common and often triggered by things we can control. Let’s talk about how we…
Management of Arrhythmias In our last week blog, we discussed the diagnostic approach to arrhythmias. This week we will focus on the management of arrhythmias. Arrhythmias are broadly classified into two categories: Management of BradyarrhythmiasHeart rate less than 60 with features of instability, such as hypoperfusion? Rule out underlying causes:…
Broadly, arrhythmias are classified into: 1: Tachyarrhythmias 2: Bradyarrhythmias
