A normal heart rhythm has two distinct beats. A whooshing sound may indicate a heart murmur, signifying atypical blood flow through the heart. This condition could be congenital or a sign of disease, and its type, along with any accompanying symptoms and potential dangers, will determine your eligibility for the DOT CDL medical exam. One common cause is anemia, characterized by a low red blood cell count, making you feel tired and weak. Carcinoid syndrome, marked by a slow-growing malignant tumor, can cause stomach pains, diarrhea, unexplained weight loss, and low blood pressure. Congenital heart defects refer to atypical heart structures present from birth, which might be symptom-free or, depending on severity, lead to sudden death. Endocarditis, a bacterial infection of the heart valves, can present with a rash, fever, or chills. Heart valve disease, where the heart valves don’t function properly, compromises circulation, leading to swelling (edema), difficulty breathing, heart palpitations, and chest pain or pressure. Hyperthyroidism involves excessive thyroid hormone production, resulting in anxiety, unexplained weight loss, feeling overly hot, and a rapid heartbeat. Lastly, hypertrophic cardiomyopathy, a heart disease that makes the heart muscle stiff or hard, can cause fainting, chest pain, difficulty breathing, fatigue, and an irregular heartbeat.
