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).
If your heart has an irregular (uneven) beat or is beating too fast, cardioversion is a way to restore a regular rhythm. Abnormal heart rhythms are called arrhythmias. There are two kinds of cardioversion. Your doctor may give you one or more medicines to bring back your regular heartbeat. This is called pharmacologic (chemical) cardioversion. Doctors also restore regular rhythms by sending an electrical shock to the heart. This is called electrical cardioversion. 1  Arrhythmias may prevent blood from circulating properly to your heart and brain. 2  Most often, doctors use cardioversion to treat a fast, irregular heart rhythm called atrial fibrillation.
