A **portable ECG machine** is a compact, user-friendly device that records the heart’s electrical activity, helping detect irregular heart rhythms and other cardiac issues. Unlike traditional hospital-based ECGs, portable versions... Read More
An **IWMI ECG** refers to an electrocardiogram (ECG) indicating an **Inferior Wall Myocardial Infarction**, a type of heart attack affecting the heart's inferior (bottom) wall, typically supplied by the right... Read More
Cardiac and skeletal muscles differ in structure, control, and function. Cardiac muscle, found only in the heart, is involuntary and contracts rhythmically without conscious control. It has striations like skeletal... Read More
A four-chambered heart, found in birds and mammals, offers significant advantages for efficient circulation. It completely separates oxygenated and deoxygenated blood through two atria and two ventricles. This separation allows... Read More
A defibrillator diagram illustrates the components and operation of a device used to treat life-threatening cardiac arrhythmias, such as ventricular fibrillation. It typically shows electrode pads placed on a patient’s... Read More
**LBBB** stands for **Left Bundle Branch Block**, and **ECG** stands for **Electrocardiogram**. An LBBB on an ECG indicates a delay or blockage in the electrical impulses traveling through the left... Read More
The human heart has five anatomical surfaces: sternocostal (anterior), diaphragmatic (inferior), base (posterior), and right and left pulmonary surfaces. The **sternocostal surface** is mainly formed by the right ventricle and... Read More
In medical terms, **DVD** stands for **Deep Venous Disease**. It refers to a condition affecting the deep veins, primarily in the legs, where blood flow is impaired due to damage... Read More
A monophasic defibrillator is a medical device used to deliver a single, high-energy electric shock to the heart during life-threatening arrhythmias such as ventricular fibrillation or pulseless ventricular tachycardia. Unlike... Read More
