A high pressure of 150 mmHg suggests the presence of hypertension. However, to diagnose hypertension, the blood pressure needs to be measured at two different times, in a quiet state. If both are higher than 140/90 mmHg, only then can hypertension be diagnosed. Occasional high pressure of 150 mmHg is not necessarily hypertension. If the blood pressure is measured during activity, anxiety, or anger, and a high pressure of 150 mmHg is found, it may be related to the emotion at that time, so you can wait until the mood swings have passed and you are quiet before taking the blood pressure. If a normal person’s blood pressure is 110-140 mmHg in a quiet state, it may not necessarily be hypertension, but can be monitored dynamically and treated in a hospital if necessary.
