Term
|
Definition
• NON-FUNCTIONING SA NODE

|
|
Term
| premature atrial contraction |
|
Definition
| this tyep of contraction shows that the SA node is not the pacemaker, compensatory pulse, pulse deficit, and a bigeminal pulse and can cause an inverted p wave and the qrs complexes can be next to each other but period will be extended |
