What are the Auricles of the Heart? The auricles, or atria, are the two upper chambers of the heart that receive blood from the body and lungs. They are separated by the interatrial septum and each atrium is connected to a ventricle by an atrioventricular valve. The right atrium receives deoxygenated blood from the body…

Bengay, a topical pain reliever, has been falsely linked to heart palpitations. Palpitations typically arise from anxiety, caffeine, or thyroid issues. Scientific studies and expert opinions refute the claim that Bengay triggers palpitations. If palpitations persist after using Bengay, seek medical attention to identify the underlying cause. Define bengay and heart palpitations State the main…

Low cardiac output syndrome occurs when the heart’s inability to pump sufficient blood impairs organ perfusion. It can result from various cardiogenic (e.g., myocardial infarction) and non-cardiogenic (e.g., hypovolemia) etiologies. Symptoms include fatigue, shortness of breath, and altered mental status. Diagnosis involves physical exam, blood tests, and imaging studies. Treatment focuses on addressing the underlying…

Sympathetic innervation of the heart arises from the thoracic sympathetic chain, with postganglionic neurons sending fibers to the atria and ventricles. These nerves release norepinephrine, which activates beta-1 adrenergic receptors on cardiac myocytes, resulting in increased heart rate, force of contraction, and conduction velocity. Vagal parasympathetic innervation also influences heart function, slowing heart rate and…

A ventricular fusion beat is a premature ventricular complex that occurs after an atrial depolarization. The P wave and QRS complex are merged, resulting in a deformed QRS complex. The P wave is usually negative, and the QRS complex has a morphology that is intermediate between that of a sinus beat and a ventricular ectopic…

Peripheral heart training focuses on improving circulation and blood flow in the body’s extremities. By targeting muscles and vessels in the limbs, this training enhances physiological entities like blood pressure, heart rate, and endothelial function. Training variables such as exercise intensity and duration play a crucial role, with moderate-to-vigorous activity, regular sessions, and adequate rest…

Excitability of Heart: The heart’s ability to respond to stimuli and generate electrical impulses depends on its excitability. During an action potential, depolarization occurs when sodium ions rush into the cell, followed by repolarization as potassium ions exit. Membrane potential and ion channels (sodium, potassium, calcium) play crucial roles. The refractory period ensures that the…

Cardiovascular research at MIT’s Media Lab explores novel biomarkers for heart health, utilizing wearable devices, sensors, and advanced data analysis techniques. These media lab cardio biomarkers aim to enhance personalized medicine, facilitate early disease detection, and provide continuous monitoring of heart function. Unlocking the Heart’s Secrets: A Journey to the Pioneers of Cardiovascular Research Groundbreaking…

The chicken heart, enclosed within the pericardium, consists of four chambers: two atria and two ventricles separated by a septum. Atrioventricular and semilunar valves regulate blood flow through these chambers. Coronary arteries and veins supply blood to the myocardium, which undergoes rhythmic contractions facilitated by the endocardium. Externally, the heart features an apex, base, pulmonary…
