Explanation:
A very early sign of transmural myocardial infarction may be an EKG with ST elevations or tall, upright
T waves. The V1 and V2 leads can be examined to see if ventricular hypertrophy is present in order to provide
a more accurate assessment.
Explanation:
Sinus pause, also known as sinus arrest, occurs when the SA node is unable to depolarize the atria. This could
result in cardiac arrest if it is not rectified by another area of the heart, such as the AV node."
Explanation:
The function of the heart is not hampered by a first-degree obstruction. Hyperkalemia, quinidine, digitalis,
and ischemic heart disease are among its possible causes.
Explanation:
Age, digitalis use, and myocardial infarction are a few factors that can contribute to a third-degree AV block.
Due to the fact that no impulses are being sent from the atria to the ventricles, this is also known as a total
heart block.
Explanation:
A patient who has a third-degree atrioventricular block in particular would be a strong candidate for
pacemaker installation. This would make up for the AV node's inability to transmit the required impulse from
the atria to the ventricles.
Explanation:
When AV node conduction becomes increasingly challenging and an EKG P wave does not follow a QRS
complex, the condition is known as a Wenckebach AV block, also known as a Mobitz I block. A second-degree
AV block is what this is.
Explanation:
The horizontal plane is where the heart's electrical activity is seen through the unipolar precordial leads. On
the chest, these leads are positioned in 6 different places.
