Premature atrial contractions (PACs) are irregular heartbeats that originate in the atria, the upper chambers of the heart. While occasional PACs are generally not a cause for alarm and can occur in individuals of all ages, including teenagers and children, it is important to be aware of when to seek medical advice. Most often, PACs...

Ventricular fibrillation, commonly known as V-fib, refers to an irregular and rapid heartbeat characterized by erratic electrical impulses. This condition disrupts the normal pumping of blood from the ventricles to the lungs and the rest of the body. With V-fib being the leading cause of sudden cardiac death, it is crucial to seek immediate medical...

Heart palpitations can be a cause for concern when you suddenly become aware of your heartbeat or experience irregular beats. While it is often nothing serious and the rhythm returns to normal on its own, it is important not to ignore these sensations. Here are ten common causes of heart palpitations: 1. Stress and Anxiety:...

Heart valve disease is a condition in which one or more of the heart’s four valves do not function properly. This diagnosis is relatively common, affecting over five million Americans annually. Normally, blood flows in one direction through the heart, from the top chamber to the bottom chamber and then to the rest of the...

Pulmonary arterial hypertension (PAH) is a serious and uncommon condition that poses a threat to one’s life. The function of the pulmonary arteries is to transport blood from the heart to the lungs, where it undergoes oxygenation before being distributed throughout the body. However, in individuals with PAH, these small arteries become constricted and narrower...

High blood pressure, also known as hypertension, is a condition characterized by the excessive speed of blood flow in your veins and arteries. When you have high blood pressure, your arteries can become rigid and narrow, impeding the optimal flow of blood throughout your body. To maintain a healthy blood flow, it is crucial to...

Arteriosclerosis is a common condition characterized by the hardening of the arterial walls. This condition, which can develop at any age, becomes more prevalent with advancing age. Arteriosclerosis occurs when the inner layers of the arteries become damaged, leading to the formation of stiff and thickened blood vessels. As a result, blood flow to tissues...

Ordinarily, the heart maintains a consistent rhythm, beating in a regular pattern. Following each heartbeat, there is a brief pause before the next one. However, individuals with bigeminy experience a peculiar irregularity in their heart rhythms, where an additional beat occurs immediately after each regular beat. This abnormal pattern is akin to twins, which explains...

Eisenmenger syndrome is a medical condition that arises as a complication of a congenital heart defect. This syndrome occurs when there is a shift in the direction of blood flow, causing oxygen-deficient blood to be pumped throughout the body. As a consequence, the tissues and organs do not receive an adequate supply of oxygen, leading...

Pericardial tamponade, also known as cardiac tamponade, is a critical medical condition that necessitates immediate medical intervention. Emergency physicians commonly refer to the region between the clavicle and the xiphoid process, located at the base of the sternum, as the “cardiac box.” Any injuries sustained in this area should be taken seriously. Pericardial tamponade occurs...
