Hypertension (HTN or HT), also known as high blood pressure (HBP), is a chronic medical condition in which blood pressure in the arteries is promoted. Cardiac Arrest and Hypertension: Hypertension (HTN or HT), also known as high blood pressure (HBP), is a long-term condition characterised by chronically elevated artery blood pressure. Symptoms of high blood pressure are uncommon. Long-term hypertension, on the other hand, is a significant risk factor for stroke coronary artery disease, heart failure and atrial fibrillation, peripheral arterial disease, vision loss, chronic kidney disease, and dementia. Hypertension is a leading cause of death worldwide. Cardiac arrest takes place when the heart stops functioning suddenly and unexpectedly. It is a medical emergency that, if not treated immediately, will result in death.
