A second degree AV block may be classified as TYPE 1( MOBITZ 1 or WENCKEBACH) or

TYPE 2 ( MOBITZ 2). TYPE 1 may be the result of a myocardial infarction ( heart attack)involving the inferior wall of the heart. Depending on the degree of damage, it may be transient and only require observation.

TYPE 2 is more serious and may be the result of a myocardial infarction ( heart attack) involving the anterior wall of the heart, which is where the heart has its pumping power. If the anterior wall of the heart is damaged and the heart's pumping power is affected, symptoms of chest pain, shortness of breath, lightheadedness and hyotension( low blood pressure)may occur.

TCP ( Transcutaneous Pacing )may be ordered by the doctor. It is often used as a bridge until a permanent pacemaker is inserted. Patients may need analgesia and sedation during this period. The doctor will order whatever is necessary to keep the patient comfortable. Assessment and documentation of the neurological , respiratory and cardiac status is essential.
