Second degree AV (atrioventricular) block is a serious and often a complicated one in the cardiac conduction system. This is determined when the AV node delays the conduction of atrial impulse. Second degree atrioventricular block part II on the other hand is a periodic atrioventricular block. Even today, it presents a significant challenge in cardiology. […]
Hydroxyzine is a medicine, primarily used to treat severe allergic reactions and belongs to the group of “Antihistamines”. However due to the recent revelation on its safety profile, Hydroxyzine for Heart Palpitations has sparked some interest in the medical arena. This drug, known for its versatility, is also prescribed for anxiety and allergic reactions like […]
A third-degree AV block develops as a result of the gradual deterioration of a second-degree AV block. It blocks impulses that would be conducted from the sinoatrial (SA) node or atrium to the ventricles. This leads to atrioventricular dissociation. Here, the atria and ventricles beat independently while coordinating with one another. A junctional escape rhythm […]
Some kinds of tachycardia are challenging to identify and treat. A broad QRS (or wide QRS) complex is also known as a broad QRS tachycardia. Wide-complex tachycardias are seen in two general forms: monomorphic and polymorphic. These differ from other tachycardia mechanisms in shape, width, and consistency. The treatment depends on the electrophysiology and the […]
Imagine being able to see the heart’s electrical activity as it unfolds, beat by beat. That’s precisely what an electrocardiogram (ECG) does – it provides a real-time glimpse into the intricate electrical dance that orchestrates the heart’s rhythm. Read on as we uncover the secrets of those mysterious ECG waves. We’ll explore how medical professionals […]
In cases of medical emergencies, identification, and treatment of life-threatening conditions like pulseless ventricular tachycardia (VT) are crucial for saving lives. Pulseless VT is basically a cardiac arrhythmia that is indicated by rapid and very disorganized electrical activity in the heart’s ventricles. This quite often leads to ineffective pumping and circulation. So, identifying pulseless VT […]
Respiratory arrest is a potentially fatal condition, where breathing completely stops. When the flow of oxygen stops, it often causes irreversible damages to the vital organs. A very recent data from the New Journal of Medicine has stated that over 1.5% of emergency admissions in the US is due to sudden respiratory arrests. There are […]
An atrioventricular (AV) of a 1st degree AV block is also known as a heart block. This blockage takes place because electrical conduction is delayed through the AV node of the heart. It slows down the impulse between the atria and the ventricles. However, the conduction between the atria and the ventricles does not have […]
Pediatric normal vital signs are the ranges that refer to the values of many physiological parameters in children. These are parameters which include the heart rate, respiratory rate, blood pressure, and also temperature. These ranges indicate the health of the child and also help healthcare professionals assess their well-being during routine checkups or other general […]
Procainamide is an antiarrhythmic medication that plays an essential role in Advanced Cardiovascular Life Support (ACLS) protocols for managing medical emergencies such as cardiac arrest. By stabilizing cardiac conduction, it efficiently treats arrhythmias encountered during resuscitation. Keep reading to explore the mechanism of procainamide ACLS and the dosages. The role of procainamide helps enhance resuscitation […]
