A Holter monitor is a portable device used to continuously record the electrical activity of the heart over 24 to 48 hours, capturing data during daily activities.

A Holter monitor helps detect and diagnose irregular heart rhythms (arrhythmias) that may not be captured during a standard ECG.

The monitor is attached to the patient with electrodes placed on the chest. It records heartbeats continuously while the patient carries out normal activities.

Patients experiencing symptoms such as palpitations, dizziness, fainting, or irregular heartbeats may require Holter monitoring to assess their heart’s electrical activity over an extended period.

Holter monitoring typically lasts 24 to 48 hours, depending on the doctor’s recommendation and the specific monitoring objectives.

The Serum Renin Test measures renin levels to assess kidney function and diagnose conditions related to blood pressure regulation and adrenal function.

You may need to avoid certain foods, activities, or medications before the test. Follow specific instructions from your healthcare provider for accurate results.

The test is often performed in the morning, as renin levels can vary throughout the day. Timing instructions will be provided by your healthcare provider.

Elevated or decreased renin levels can indicate conditions such as secondary hypertension, kidney disorders, or adrenal dysfunction. Further evaluation may be needed.

Results are generally available within 24 to 48 hours after the blood sample is collected, allowing for prompt review and diagnosis.

Conditions such as aneurysms, peripheral artery disease (PAD), blood clots, carotid artery stenosis, and varicose veins can be treated using endovascular techniques.
