How to Read an ECG

!±8± How to Read an ECG

The electrocardiogram or ECG is a medical device that measures the electrical activities of the heart using electrodes placed in certain positions on the body. Physicians use the information gathered from the device to record the heart rate, myocardial infarctions, arrhythmias, ventricular hypertrophies, atrial enlargements, and bundle branch blocks.

The ECG gives out ten basic pieces of information about the heart. They are the following:

1. Rate. To determine the rate, consider two durations of identical points in a consecutive ECG waveform (R-R interval). Take this duration and divide it into 60. The equation should be: Rate = 60/(R-R interval)

2. Rhythm. This includes normal sinus rhythm (NSR), regular, and irregular rhythm.

3. Axis. The basic principle in finding the axis is searching for the lead whose QRS complex is closest zero.

4. P Wave Morphology. Generally, the P wave should neither measure more than one box wide nor one box tall. If it exceeds these, it means that either or both atria is enlarged and the patient is hypertrophied. V1 is the best lead to look for the P wave.

5. PR Interval. The PR interval defines AV conduction time which is usually between 0.12 - 0.20 milliseconds (or three to five boxes wide). An AV block is present if the PR interval is more than 0.2 seconds.

6. QRS Complex Morphology. This is not so easy to interpret. However, stepwise evaluation can be helpful. The following are the things to consider:

- Duration should be between 0.08 - 0.10 seconds (or 2 - 2.5 boxes) only.

- Presence of Q waves (a Q wave should be greater than one box wide).

7. ST Segment Morphology. This can determine whether ischemia or infarction is present. In general, ischemia is indicated with a depressed ST segment while an elevated ST segment confirms that there is infarction.

8. T Wave Morphology. T waves generally point to the same direction as the QRS's largest deflection. Changes in the T waves can be usually associated with ischemia, hyperkalemia, and hypokalemia.

9. U Wave Morphology. The presence of U waves may indicate hypokalemia.

10. QTc Interval. With quinidine toxicity, Qtc interval is lengthened. It is shortened with hypocalcemia.

The EKG - There's Nothing to Fear

!±8± The EKG - There's Nothing to Fear

If you ever visit your health care provider with concerns about a possible heart condition, or if you have a hereditary risk of heart disease, he or she may arrange for a screening test known as an EKG or ECG. A lot of individuals become uneasy when they're supposed to take medical tests, but the fact is that this particular test is non invasive and might in fact save your life.

ECG and EKG are acronyms for a medical screening known as an electrocardiogram. This test measures the electrical activity of your heart. While a stethoscope can permit a physician to listen to your heart, the EKG lets him or her view the electrical current of the pulsing heart.

The heart pulsates in three different waves. The first movement is the P wave. It occurs when the right and left atria beat. These are the upper chambers of the heart that collect blood from the circulatory system and the lungs. The next wave is known as the QRS complex and is produced by the lower chambers of the heart known as ventricles. These are the elements of the heart that propel blood away from the heart. The last wave is named a T wave and it leads to the replenishment of the ventricles after they pulsate.

A doctor can learn lots of information about your heart by examining this pattern of waves. The EKG will reveal how long it takes electrical activity to move across the heart. If it's moving very quickly or too slowly, this information will help your physician make a diagnosis of your problem. The assessment will also reveal if there are specific parts of the heart that are operating inadequately by measuring how much electrical activity is present in them.

When you undertake this assessment, some stickers will be placed around your torso close to the heart. These will be joined to thin cables that lead to the ECG device. While the test is being performed, the appliance measures your electrical activity. After the assessment is completed, the sticky pads are removed. Taking off the stickers is the most uncomfortable part of the whole procedure. The rest is perfectly comfortable because the apparatus is not shooting any kind of electrical current into your system. It's only measuring the electrical activity within you.

The ECG is one of the most universally utilized tests for diagnosis of heart conditions. After you undergo this assessment, the results could lead to a diagnosis or to additional testing to pin down the specific ailment. Tests like an echocardiogram may be called for. The echocardiogram is an ultrasound of the heart and is also painless and noninvasive.

Lyrics: ---------------------------------------- ---------------------------------------- I was in love with an Albino Her lack of pigment seemed like fun Her skin, the whitest alabaster Her eyes as pink, as pink as bubble gum Then one day it snowed real hard And she disappeared... I love little Agnus Johnson I met her at the old folks home She'd call me up and say "Hey Stephen Come give old Mother a bone!" Then one day her EKG went... Beep, beep, beeeeeeeeeeeeeep ---------------------------------------- ----------------------------------------

EKG Machines For Assessing Heart Function

!±8± EKG Machines For Assessing Heart Function

As a result of electrocardiogram machines, doctors are able to easily diagnose many heart diseases. What is an electrocardiogram machine? Many people are not familiar with this term. EKG is the term that is commonly used to refer to an electrocardiogram machine. This article will give you some information about electrocardiogram machines.

As with practically everything in this modern world, technology has allowed doctors to miniaturize the electrocardiogram machine. To understand why this is such a beneficial thing, we must consider the past of the device. The original machines were huge, and required physical wiring to detect and send heart signals. The present device is centered around easily placed electrodes, allowing physicians (and their patients) a better, more rapid look at exactly what cardiac issues are happening.

Several doctors want the electrodes of the electrocardiogram machine to be attached when the patient is performing exercise such as walking on the treadmill or riding on a stationary bike. Through this it helps the doctor to know much better about the functions of the heart, which is undergoing physical strain.

Graphs that represent various bodily functions and rhythms can be created by placing electrodes on various parts of a patient's body and then transmitting the electrical impulses they receive through cables that are connected to a electrocardiogram machine. The machine has a digital screen that the doctor can use to monitor these amplified electrical pulses. Hospitals make use of ekg machines all throughout the world.

There are too many benefits of 'ekg machines' to list them all here. It is true that using 'ekg machines', otherwise known as 'ecg machines', doctors have saved millions of lives all over the world. 'Ecg machines' are sold by numerous stores on the Internet.

Purchasing used medical equipment is an option for people who cannot afford to buy brand new "ekg machines". Used medical equipment is sold by many vendors. There are numerous well known companies which manufacture quality "ekg machines". Performing a search on the Internet will give you a better idea about the features included on up-to-date electrocardiogram machines.
