A small amount of blood is taken from a vein in your arm with a needle. The blood is collected in tubes and sent to a lab. Ask your healthcare provider when and how you will get the results of the test. What does the test result mean? A PT/INR value higher than normal means your blood is taking longer than normal to form a clot. If you are taking a blood thinner, it means that the medicine is working. If you are not taking a blood thinner and your values are higher than normal, you may: Have liver disease
The normal heart rhythm (normal sinus rhythm) shows the electrical activity in the heart is following the normal pathway. The rhythm is regular and the node is normal (about 50 to 100 beats per minute).Tachycardia: fast heart rhythm (greater than 100 beats per minute).he normal heart rhythm (normal sinus rhythm) shows the electrical activity in the heart is following the normal pathway. The rhythm is regular and the node is normal (about 50 to 100 beats per minute).
Normal Sinus Rhythm. Description. A normal heart rhythm is called normal sinus rhythm (NSR for short). An NSR will have a heart rate (this is the same as the pulse) between 50 and 100 beats per minute and a normal impulse formation from the SA node (P wave).lso, all the waveforms must be of a normal shape with no ST changes. In children, normal heart rate ranges are much higher. Infants to 1 year have a normal range to 180 beats per minute, 1-3 years to 150 beats per minute, 4-10 years to 130 beats per minute and 110 beats per minute to age 16.
