What is the first -degree AV block?
Atrioventricular (AV) first stage block is a change in the normal heart rhythm where the electrical signal between the atrial and the chamber is slightly delayed. This condition usually does not cause any symptoms and it can be a random finding during a routine examination for unrelated health problems. Treatment is not generally required unless there is concern that the first -level AV block can proceed to a more serious heart block, which may be a problem if the patient has a basic health problem.
In the patient with AV first stage block, the PR interval is interval, which is the amount of time needed to signal for travel from the atrie to the chamber, is greater than 0.2 seconds. In healthy individuals, this interval is less than 0.2 seconds. The PR interval can be clearly seen in electrocardiography, allowing a physician to diagnose a patient with AV first stage block.
athletes commonly show this formula in the electric signals of their hearts as a result of an increase in vagal tone, which means they are experiencing a higher level of pulses from the vag nerve,which causes inhibition or stress of heart rhythm. People can also develop this situation in conjunction with a number of infectious diseases and heart valves. The patient generally does not experience any problems due to a slightly prolonged PR interval. If this condition is identified, the patient may be evaluated to other risk factors to see if monitoring is required in the future.
One concern and the first grade block is the risk that it can proceed to a complete block of AV, where the signal does not reach the chambers at all. If the patient has a different heart problem or has a heart attack, there is a risk of escalating the severity of the condition. Medicines can be provided and it is possible to the patient to need a mechanical pacemaker in the future to control the heart rhythm and maintain the heart normally.
Many people live with a block of first degree AV and do not know about the state. Others have it diagnosed during a routine medical examination and may not have to take any further steps to solvethe abnormal heart rhythm. In cases where this is a reason for concern, the doctor may discuss how to proceed in case and provide information on the patient treatment options. Treatment may vary from mere request of the patient to undergo regular electrocardiograms to check the signs of changes in the recommendation of an artificial cardiac for the patient's heart rhythm.
