|
Definition
| FIRST CALCULATE THE BLOOD VOLUME, MULTIPLY BY 0.9 AND YOU'VE GOT CARDIAC OUTPUT. |

Term
| DESCRTIBE THE 300 METHOD. |
|
Definition
| THE METHOD FOR CALCULATED HR. ALL YOU DO IS FINE AN R WAVE AND COUNT HOW MANY DARK LINES ARE BETWEEN THEM. <1 HR>300 1 DARK LINE 300, 2=150, 3=100, 4=75, 5=60, 6=50 |

|
Definition
| DISTANCE BETWEEN SUCCESSIVE R WAVES |
|

|
|
Term
| WHAT HAPPENS AS YOU TAKE A DEEP NEGTIAVE BREATH? |
|
Definition
| INTRAPLEURAL PRESSURE DECREASES, THAT INCREASES THE VENOUS RETURN TO THE RIGHT SIDE OF THE HEAT AND INCREASE VOLUME MEANS THAT I HAVE TO HAVE AN INCREASED RATE TO KEEP UP. |
|
|
Term
| WHAT HAPPENS WITH YOU HAVE A POSITIVE BREATH? |
|
Definition
| INTRAPLEURAL PRESSURE IS GOING TO INCREASE, VASCULAR RESISTANCE IN THORACIC CAVITY INCREASES, THEREFORE THE VENOUS RETURN IS GOING TO DECREASE. |

|
Term
| WHERE ARE THE P WAVES WITH AN IDIOVENTRICULAR RHYTHM? |
|
Definition
| HIDDEN IN MY QRS COMPLEX R/T RETROGRADE PROGRESSION OF THE WAVE OF DEPOLARIZATION. |
|
|
Term
| WILL YOU SEE T WAVES IN IDIOVENTRICULAR RHYTHM? |
|
Definition
| YOU MAY OR MAY NOT SEE INVERTED T WAVES |
|
|
Term
| DESCRIBE HOW V-TACH HAPPENS. |
|
Definition
| SLOWED CONDUCTION IN MARGIN OF ISCHEMIC AREA PERMITS CIRCULAR COURSE OF IMPULSE AND REENTRY WITH RAPID REPETITIVE DEPOLARIZATION. |

| HOW CAN YOU DISTINGUISH A NON-SINUS ATRIAL RHYTHM? |
|
Definition
| INVERTED P WAVES ON LEAD II,III, AND AVF. |
|
|
Term
| WITH NON-SINUS ATRIAL RHYTHM DESCRIBE THE WAVE OF ATRIAL DEPOLARIZATION. |
|
Definition
| IT IS MOVING TOWARDS THE NEGATIVE ELECTRODES. |
|
|
Term
| WHERE IS THE PM AT FOR NON-SINUS ATRIAL RHYTHM? |
|
Definition
| NOT THE SA NODE. ATRIAL ECTOPIC PM. |
|
|
Term
| TYPICALLY, WHAT ARE THE PRI FOR A NON-SINUS ATRIAL RHYTHM? WHY? |
|
Definition
| SHORTENED BECAUSE THE ATRIAL ECTOPIC PM IS CLOSER TO THE AV NODE. |
|
|
Term
| FOR A NON-SINUS ATRIAL RHYTHM WHAT WOULD YOU FORMULATE WHEN YOU SEE INVERTED P WAVES IN LEAD I? |
|
Definition
| THE WAVE OF DEPOLARIZATION IS GOING FROM LEFT ATRIA TO RIGHT ATRIA. |

Definition
| THEY ARE INVERTED R/T PM IS COMING FROM A DIFFERENT AREA. THE QRS CAN BE REGULAR OR IRREGULAR. THE P WAVES ARE REGULAR AND OFTEN INVERTED. |
|
|
Term
| DESCRIBE THE WAVE OF DEPOLARIZATION WITH A-FLUTTER. |
|
Definition
| THE WAVES OF DEPOLARIZATION ARE SPINNING IN CIRCLES. THIS PRODUCES SIGN WAVES. |
