CRTD is a combo device with capabilities of bi ventricular pacing and intra cardiac defibrillation . It is indicated in severe LV dysfunction with wide QRS on ECG who are in NYHA class III-IV .

Optical coherence tomography (OCT) is a diagnostic procedure that is used during cardiac catheterization. Unlike ultrasound, which uses sound waves to produce an image of the blood vessels, OCT uses light. With OCT, doctors can obtain images of the blood vessels that are about the same as if they were looking under a microscope. The main applications of the OCT system are: 1. Atherosclerotic plaque assessment 2. Stent struts coverage and apposition assessment, and in stent restenosis evaluation 3. PCI guide and optimisation

Ambulatory Blood Pressure Monitoring (ABPM) measures your blood pressure over the course of a full day (24 hours). You will wear a blood pressure cuff on your upper arm that is connected to a monitor. The monitor records your blood pressure readings 3 times per hour while awake and 1 time per hour while sleeping. Measuring your blood pressure in your normal environment and during your usual daily routines gives your doctor a better idea of how your blood pressure changes throughout the day. Some reasons for having ABPM: 1. White coat hypertension: high blood pressure in clinic settings (around medical staff or doctors) with lower blood pressure outside of clinic. 2. High blood pressure without a diagnosis of hypertension: blood pressure may be high sometimes and more blood pressure measurements are needed. 3. Hypertension medicine assessment: to make sure your blood pressure medicines are working as they should all day. 4. Assess symptoms - such as lightheadedness, dizziness, or headaches, to check if these are due to blood pressure.

A Holter monitor is a battery-operated portable device that measures and records your heart’s activity (ECG) continuously for 24 to 48 hours or longer depending on the type of monitoring used. The device is the size of a small camera. It has wires with silver dollar-sized electrodes that attach to your skin. The Holter monitor and other devices that record your ECG as you go about your daily activities are called ambulatory electrocardiograms. Wearing the monitor may tell your doctor: If your medicines are working. Why you have symptoms such as dizziness, faintness or the feeling that your heart is racing or skipping a beat. If your heart is getting enough oxygen to meet its needs.
