Right Ventricular Hypertrophy and the ECG

Abbreviations: ECG – electrocardiogram RAD – right axis deviation RVH – right ventricular hypertrophy ECGs are good screening tests to look for certain cardiac abnormalities. There are distinct ECG criteria identifying right ventricular hypertrophy (RVH), which can be easily memorized and ascertained with a little knowledge of cardiac anatomy and electrical conduction properties. Below, I […]

Understanding ECGs – Define, Deduce, and Diagnose (Part 1)

What is the best way to understand an issue? I try to define the terms, deduce how everything fits together, and then make a diagnosis. Reading electrocardiograms (ECGs; EKGs) is no different – Define, Deduce, and Diagnose. As basic as this may sound, interpreting an EKG takes knowing the basic definitions of the waveforms, understanding […]

Differentiating Atrioventricular (AV) Blocks

Differentiating atrioventricular (AV) blocks is a simple process as long as you understand some of the patterns. Here I will explain the different AV blocks, describe the part of the AV nodes involved in each block, and then show you how to figure one out from the other. These are all explained further and with […]

ACLS Rhythms – Learn The Terminology, Definitions, and Pathophysiology

Almost all medical professionals require certification in Advanced Cardiac Life Support (ACLS) to work in the hospital or many medical facilities. Not only that, but they need to recertify in ACLS every two years. Trainees of ACLS learn how to treat cardiac emergencies like a myocardial infarction (heart attack), cardiac arrests, and life-threatening arrhythmias […]

What is an rSR Prime (rSR’)?

Sometimes an electrocardiogram (ECG) reader will mention an rSR’ on the ECG reading. Sounds really important, doesn’t it? In reality, most of the time it is a benign finding. Here, I will tell you what is an rSR prime (rSR’), and some of the common and uncommon etiologies. First, The QRS Complex Not to belittle […]

What To Expect From A Good Holter Monitor Reading

My patient complained of palpitations. I ordered a 24-hour Holter monitor. Nothing is more frustrating than receiving a report stating “arrhythmias seen, no diary submitted,” and then finding out from the patient that they were never asked to even keep a diary during monitoring. From my perspective, the patient’s time and money, as well as […]

How To Read An ECG: Learn The ECGEDU Approach To Reading ECGs

While it may seem like a complex concept, with the right instruction, learning how to read an ECG is a lot less daunting than it may seem. The real trick to learning to read and interpret ECGs is to follow a system. A systematic approach, such as the one taught in our ECG interpretation courses, […]

The Heart Failure Syndrome

Heart failure (HF), also called congestive heart failure, is one of the most common hospital diagnoses and therefore is encountered by almost every medical specialty. This article summarizes and simplifies HF. What Is Heart Failure Although HF is a diagnosis upon itself, I view it as a clinical syndrome that always has another […]
