Why You Really Need NORMAL ECG

 

Introduction

ECG is a diagnostic tool that helps to rule out cardiac diseases. It is made up of several waves which can be seen on the ECG monitor. The heart beats 60 times per minute and each heart beat results in the formation of an electrical impulse (a tiny jolt) as electricity passes through your body’s tissues. This impulse travels through your body along pathways called conduction pathways, which include arteries and veins (blood vessels). These pathways carry electrical impulses from one part of the heart to another via arteries or veins on their way towards your brain so they can be detected by sensors placed on top of your chest bone called electrodes.

What is ECG?

ECG is short for electrocardiogram, which is a test that measures the electrical activity of your heart. It's used to diagnose and treat heart conditions such as arrhythmia (irregular heartbeat), atrial fibrillation (fluttering of the upper chambers), ventricular tachycardia (an abnormally fast heartbeat), and Wolff-Parkinson-White syndrome. In addition, it can help doctors monitor the effects of chemotherapy on your heart.

How to read ECG?

An ECG is a graphical representation of the electrical activity of the heart. It's easy to understand when you look at it, but it's also helpful to know how to read an ECG.The normal sinus rhythm is one that goes on for about 40-60 beats per minute and then pauses at regular intervals before starting again. When this happens over and over again, it forms what's called a sinus node (the part of your heart that controls its rate). If there isn't enough blood flow through this part or if something else prevents it from working properly, your body will have problems keeping up with its normal functions like breathing or digestion—and these can be life-threatening!

what is P wave

The P wave is the first wave of your ECG. It represents atrial depolarization and its height indicates the rate of depolarization (or conduction velocity). In other words, if it’s tall and wide in your lead II then you have fast heart rate and good sinus rhythm; if it's short and narrow, then you have slow heart rate or non sinus rhythm.Inverted P waves are common in patients with ventricular arrhythmias or ST-segment elevation myocardial infarction (STEMI), but they can also occur in other conditions such as Wolff-Parkinson-White syndrome (WPW) or idiopathic ventricular tachycardia (VT).

what is QRS wave

The QRS complex is the first part of your heart's electrical R-wave and S-wave. It starts at the beginning of each heart beat, and is represented by three distinct deflections:

• First deflection – called the Q wave (or "interventricular")

• Second deflection – called an R wave (or "atrial")

• Third deflection – called an S wave

what is T wave

The T wave is the last part of the ECG and represents repolarization of the heart muscle.The normal voltage gradient across your heart will cause depolarization, or an increase in electrical charge at one pole (positive) to another (negative). This process causes sodium ions to flow out of solution into your cells, causing them to become more negative than they were before. This leads to an increase in conductivity between them, which then results in contraction of muscles within your heart's chambers.

The T wave represents this repolarization process by showing you how much time has passed since it started until now - it should be tall and narrow when seen on an ECG strip because it's a sign that there's not enough time for any more electrical activity yet!

what is ST segment

ST segment is the flat part of the ECG. It's the last segment before the T wave and it looks like this.

The ST segment is between two waves (P and T). It usually occurs after a pause in ventricular activity, which means that it can be used to determine if there was an arrhythmia or not.

what is U wave

The U wave is a small and flat wave that appears after the T wave. It can be seen in situations where there is no significant change in heart rate or blood pressure, such as during exercise or while resting.

This type of “normal” ECG tracing has been observed to occur over 1 million times per day in healthy people with no abnormalities on their electrocardiograms (ECGs). It is also not associated with heart disease or other serious concerns such as coronary artery disease or aneurysms.

ECG helps to rule out cardiac diseases.

The ECG is a non-invasive test that helps to rule out cardiac diseases. It also helps to diagnose heart problems, as well as find out if you are at risk of having a heart attack or stroke.

The benefits of the ECG include:

• The test can be done by your doctor or nurse practitioner in their office with minimal discomfort. There is no need for you to go into the hospital for this procedure and there's no need for an overnight stay after the procedure either!

Conclusion

ECG is a useful tool for doctors and patients. It helps to rule out cardiac diseases quickly and accurately, which is important in the early diagnosis of heart problems. This technique can also be used to detect other conditions such as arrhythmia or electrolyte imbalances.
