Blood pressure is a force of circulating blood on the walls of arteries. Generally, we measure blood pressure in two terms systolic and diastolic. The normal blood pressure range is 120 /80mmHg. High blood pressure is 140/90mmHg or higher and low blood pressure is 90/60mmHg or lower. High blood pressure is known as a silent…
The heart is a vital part of our body. It gives blood to the other parts of the body. Every heartbeat sends blood to blood cells. The weight of the heart is between 300 to 450 grams and the size of the heart is equal to a clenched fist. The heart gives oxygenated blood and…
Blood pressure below 90 mm Hg (millimeters of mercury), in the case of the higher number – systolic pressure – and 60 mm Hg for the lower number (diastolic blood pressure) is considered, in general, arterial hypotension. Warning signs It is desirable to have low blood pressure – this does not cause problems for some…
Tachycardia is a heart rhythm disorder that involves the appearance of an accelerated pulse of over 100 beats/minute. The increase in heart rate that exceeds this value and does not present an obvious physiological cause such as fast walking, intense physical effort or stress, indicates the existence of a tachycardia with a pathological substrate that…
Myocarditis is an inflammation of the myocardium of various etiologies that causes heart rhythm disorders interfering with the specific activity of the heart pump and affects especially young adults and children. Myocarditis: etiology, symptoms and investigations What are the causes of myocarditis? Symptoms of myocarditis Diagnosis of myocarditis Treatment of myocarditis Myocarditis is an inflammation…
Cardiac ischemia is frequently caused by obstruction of a coronary artery with lipid fragments detached from endovascular atheroma plaques, but it can also be due to a functional vasospasm caused by exertion or exposure to extreme temperatures. What is cardiac ischemia Why does coronary hypoperfusion occur? What are the symptoms of cardiac ischemia Diagnosis of…
Heart failure, also known as congestive heart failure, is a condition manifested by the inability of the heart to pump enough blood to the organs and tissues of the body. When it occurs, heart failure causes pulmonary stasis with fluid accumulation in the lungs (pulmonary edema) and dyspnea. Certain cardiovascular pathologies with chronic evolution, such…
Blood pressure (BP) represents the pressure exerted by the blood column on the inner lining of blood vessels, called the vascular endothelium, during myocardial contraction (systolic blood pressure) and cardiac relaxation (diastolic blood pressure). Systolic pressure refers to the pressure exerted on the arterial walls during cardiac contraction and is physiologically between 100 and 130…
Hypotension is a condition characterized by the presence of systolic blood pressure <90 mm Hg and diastolic blood pressure <60 mm Hg. Blood pressure is physiologically lower at night and rises suddenly upon waking up from sleep and can vary during the day depending on body position, respiratory rate, food and fluid intake. What is…
Arterial hypertension is represented by increases in systolic blood pressure above 140 mmHg and diastolic blood pressure above 90 mmHg. What is hypertension Why does the condition occur? What are the symptoms of high blood pressure? The diagnosis of arterial hypertension Treatment of hypertension What is hypertension Arterial hypertension is represented by increases in systolic…
