This review will cover the differences between premature ventricular contractions (PVCs), premature atrial contractions (PACs), and premature junctional contractions (PJCs). Don’t forget to check out all of our EKG interpretation reviews and to watch the lecture on PVCs vs. PACs vs. PJCs. Premature Ventricular Contractions (PVCs) Premature Ventricular Contractions (PVCs) are early contractions that originate […]

Premature junctional contractions (PJCs), also called premature junctional complexes, are early heartbeats that originate from the AV junction instead of the SA node. Understanding PJCs is essential for nursing students preparing for exams like the NCLEX and for clinical practice. This guide breaks down everything you need to know in an easy-to-follow format. What Are […]

Premature atrial contractions (PACs) are early heartbeats that originate from a focal point in the atria, rather than the sinoatrial (SA) node. These early beats cause the atria to contract prematurely. PACs are sometimes referred to as “PACs,” and they can be seen in a variety of rhythm patterns. After reviewing this material, don’t forget […]

Premature Ventricular Contractions (PVCs) are early contractions that originate in the ventricles, the bottom chambers of the heart. These contractions are typically caused by ventricular irritability. PVCs can occur suddenly and disrupt the normal electrical conduction process in the heart. Don’t forget to watch the premature ventricular contractions (PVCs) lecture and to take the quiz […]

ECG/EKG Interpretation Study Guide and Workbook by Nurse Sarah! This book contains Nurse Sarah’s own personal notes and memory tricks to help you learn and retain important ECG concepts for nursing school, nursing exams, and while working as a nurse. Nurse Sarah has condensed and illustrated her YouTube lectures into these easy-to-read study notes for […]

This abnormal rhythm originates from the electrical components within the AV junction, such as the AV node or the bundle of His. These structures exhibit increased automaticity, causing them to fire more quickly than usual. However, the primary pacemaker of the heart, the SA node, is unable to function as the main conductor due to […]

This abnormal rhythm originates from the electrical components in the AV junction, primarily the AV node or potentially the bundle of His, as a result of increased automaticity. This indicates that the cells in the AV node are more energized than usual, leading to accelerated function, resulting in the heart beating consistently without external stimulation. […]

This abnormal rhythm occurs when the primary pacemaker of the heart (SA node) functions too slowly or malfunctions. Consequently, alternative pacemaker structures located in the AV junction of the heart initiate the heartbeat. These structures serve as a backup, preventing the heart from entering cardiac standstill, as they step in when the SA node fails […]

Angina is a fancy term for chest pain. This is a type of chest pain that occurs when blood flow to the heart muscle (hence the myocardium) is restricted by the coronary arteries. Chest pain is a warning sign from the body that the heart is not receiving enough blood, and if it doesn’t get […]

Learn about First, Second, and Third degree AV heart blocks in this comprehensive ECG review. Each section will review the four different types of heart blocks and have a link to a review quiz afterwards. Also, here is a lecture on heart blocks available to watch: First-Degree AV Heart Block Characteristics and Criteria of First-Degree […]

As a nurse you want to be familiar with different types of heart rhythms, especially ones that most commonly affect patients like atrial flutter. Before reviewing these lecture notes, don’t forget to watch the lecture on atrial flutter. A-flutter is a rhythm that is similar to atrial fibrillation in that the atria are not firing […]

As a nurse you want to be familiar with different types of heart rhythms, especially ones that most commonly affect patients like atrial fibrillation. Before reviewing this lecture notes, don’t forget to watch the lecture on atrial fibrillation. Atrial fibrillation, also known as a-fib, is one of the most common rhythms seen in a hospitalized […]

As a nurse you want to be familiar with different types of heart rhythms, especially life-threatening rhythms like ventricular fibrillation (v-fib). Before reviewing these notes, don’t forget to check out the lecture on ventricular fibrillation (v-fib). Ventricular fibrillation (v-fib) is a deadly rhythm that leads to death if not reversed and treated within minutes. This […]

As a nurse you want to be familiar with different types of heart rhythms, especially life-threatening rhythms like Pulseless Electrical Activity (PEA). Before reviewing these notes, don’t forget to check out the lecture on Pulseless Electrical Activity (PEA). Pulseless Electrical Activity (PEA) How to identify it? This rhythm looks like an organized rhythm, but the […]
