(grimes). Non-cardiac syncope can be caused by many of the physiologic processes in the human body. This includes seizures‚ situational occurrences‚ hyperventilation‚ metabolic diseases‚ and orthostatic hypotension. Of the reasons above listed‚ the most common in the dental field is the orthostatic hypotension. This is caused due

Pheochromocytoma‚ a rare condition caused by a tumor in the adrenal medulla affecting the chromaffin cells‚ results in an excess production of catecholamines (epinephrine and norepinephrine) and metanephrines. The most immediate effect of this condition is severe hypertension‚ but other symptoms (such as headache‚ palpitations and excessive generalized sweating) can also appear. If left untreated‚ pheochromocytoma may lead to hypertensive encephalopathy‚ cardiomyopathy‚ diabetes mellitus and even

The cardiovascular system plays a crucial role in pumping blood‚ nutrients‚ and respiratory gases throughout the body. Blood pressure is the force that pushes blood against the blood vessel walls and delivers these essential elements to the body. The highest pressure is when the artery is maximally stretched and is recorded as the systolic pressure. The lowest pressure occurs when the artery recoils and is relaxed is known as the diastolic pressure. Mean arterial pressure is the average blood pressure
