A care plan for myocardial infarction outlines comprehensive nursing interventions to care for patients who have experienced a heart attack. It encompasses assessment and monitoring, medication management, emotional support, and discharge planning. This plan emphasizes the importance of invasive treatments such as PCI and CABG, while highlighting the role of nursing in promoting rehabilitation, lifestyle…
Paradoxical splitting of second heart sound occurs when the aortic component (A2) closes slightly before the pulmonary component (P2) in expiration. This is due to increased intrathoracic pressure during expiration, which decreases systemic venous return and right ventricular preload, resulting in delayed closure of P2. Normally, P2 closes before A2 (physiological splitting). Paradoxical splitting suggests…
The apex of the left ventricle is the lower, pointed tip of the heart’s left chamber. It plays a crucial role in the heart’s pumping action, contracting during systole to expel blood from the left ventricle into the aorta. The apex is connected to the interventricular septum, aortic and mitral valves, and papillary muscles. Abnormalities…
The conus arteriosus is a vital part of the heart’s outflow tract, responsible for directing blood flow from the ventricles to the aorta and pulmonary artery. During embryonic development, it undergoes conal septation, dividing it into the aortic and pulmonary conus, contributing to the formation of the great vessels. The conus arteriosus plays a crucial…
Supracristal ventricular septal defect (VSD) is a rare congenital heart defect characterized by a hole in the ventricular septum located above the crista supraventricularis, a muscle ridge in the heart. This defect allows oxygenated and deoxygenated blood to mix, leading to symptoms such as cyanosis (bluish tint to the skin) and heart failure. Supracristal VSD…
Gap junctions, connexins, and electrical coupling are essential for synchronized heart contractions. Intercalated discs, connexin gene expression, and automaticity contribute to heart rhythm regulation. Myocytes, computational modeling, and stem cell therapy hold promise for understanding and treating heart conditions. The Heart’s Electric Highway: Gap Junctions and the Rhythm of Life The heart, a tireless pump…
Split ventricle syndrome, a rare congenital heart condition, arises from a split in the ventricle wall, commonly associated with heart defects like double outlet right ventricle and tetralogy of Fallot. Genetic disorders, such as 22q11.2 deletion syndrome, contribute to its development. Symptoms include cyanosis, shortness of breath, and growth issues. Diagnosis involves echocardiography, MRI, and…
