What are cardiac monitors?

Posted by: Johnson Francis on: 18 May, 2012

Cardiac monitors are devices with displays to show ECG, heart rate and other parameters on a continuous basis, usually used in the intensive care unit or operation theatre. Earlier cardiac monitors had just ECG and heart rate displays. Current multi parameter monitors have invasive and non invasive blood pressure, respiration, pulse oximetry, pacemaker sensing and various other monitoring possibilities. It can give out alarms if heart rate or any other parameter is beyond the set limits. Some times the number of alarms are so many that ICU staff may develop “alarm fatigue” and stop responding to alarms. Hence alarm limits should be set appropriately and monitoring should be done only when essential.

Can a teenager have heart disease?

Posted by: Johnson Francis on: 18 May, 2012

No age is exempt from heart disease, but some forms of heart disease like a heart attack are quite rare in teen agers. Still teen agers can have heart attack if they are heavy smokers, have a strong family history of premature heart disease, or familial disorder with very high blood cholesterol. Other forms of heart disease which can occur in teen agers are congenital heart disease (birth defects of the heart) and rheumatic heart disease (disease of heart valves following rheumatic fever in childhood).
