Hemodynamic Monitoring and the Heart

QuestionAnswer
What is it called when your heart skips a beat, has irregular rhythm, normal P waves and QRS complex missing? 2nd Degree Heart Block
How is 2nd Degree Heart Block Treated? Atropine and and electrical pacemaker
What is it when the PR interval cannot be determined and the QRS complex is widened? 3rd Degree Heart Block
How is 3rd Degree Heart block treated Electrical Pacemaker
What degree of block slows you down, pauses between the P wave to the QRS complex? 1st Degree Heart block
How is 1st Degree Heart block treated Atropine
What does an inverted T-wave mean Myocardial Ischemia
What does significant Q waves mean? Myocardial Infarction
What do elevated S-T segments mean Myocardial Injury
Where is the SA Node located? Upper right hand corner of the heart.
How does the electrical impulse travel through the heart Moves through atria causing contraction (P-wave), then it is received by AV node, delayed (P-R interval). Stimulus is sent through bundle of His and L&R bundle branches to purkjunke fibers (QRS) after short delay (S-T) the heart depolarizes (T-wave).
How do you treat Asystole Confirm in 2 leads first, epinephrine , Atropine and CPR
How do you treat Sinus Bradycardia Oxygen, Atropine
How do you treat Sinus Tachycardia Oxygen
How do you treat PVC Oxygen, Lidocaine
How do you treat multifocal PVC Oxygen, Lidocaine
How do you treat Ventricular Tachycardia If no pulse De-fibrillate If pulse Lidocaine, Cardioversion
How do you treat Ventricular Fibrillation De-fibrillate
Where do you place the Chest Electrodes V1 for an EKG 4th intercostal space on R side of sternum
Where do you place the Chest Electrodes V2 for an EKG 4th intercostal space on L side of sternum
Where do you place the Chest Electrodes V3 for an EKG Between V2 and V4 on left side
Where do you place the Chest Electrodes V4 for an EKG 5th intercostal space,left mid-clavicular line
Where do you place the Chest Electrodes V5 for an EKG Between V4 and V6 on left side
Where do you place the Chest Electrodes V6 for an EKG 5th intercostal space, left mid-axillary line
Two factors that affect the direction of the axis Hypertrophy and Infarction
What is the normal axis of the hearts electrical impulse Down and to the left
What are the 4 Chambers of the Heart Left Ventricle Right Atria Right Ventricle Left Atria
The Left Ventricle serves what branch systemic arteries
The Right Atria serves what branch systemic veins
The Right ventricle serves what branch pulmonary arteries
The Left Atria serves what branch pulmonary veins
What are the 3 factors which control blood pressure Heart, Blood and vessels
How does the heart increase BP when the rate increases
How does blood increase BP when there is fluid overload
How do vessels increase BP when there is constriction of the vessels
How does the heart decrease BP When it is not pumping hard enough
How does blood decrease BP Loss of blood
How do the vessels decrease BP when there is dilation of the vessels
List two methods used for measuring MAP Indwelling arterial catheter with a pressure transducer.
The left heart is associated with what disease CHF
The right heart is associated with what disease Cor Pulmonale
What is pulse pressure The difference between the systolic and diastolic pressure
What is Cardiac Output (QT) Measures the output of the left ventricle to systemic arterial circulation
What is SVR-Systemic Vascular Resistance The pressure gradient across the systemic circulation divided by the cardiac output
What is PVR - Pulmonary Vascular Resistance The pressure gradient across the pulmonary circulation divided by the cardiac output
What causes PVR to increase hypoxia, pulmonary hypertension and lung disease
What is the Normal Cardiac output range 4-8 LPM
What is the normal Cardiac Index range 2.5-4.0 liters/min/m2
The first heart sound S1 is created by what Normal closure of the mitral and tricuspid valves at the beginning of ventricular contraction
The second heart sound S2 is created by what Systole ends. The ventricles relax and the pulmonic and aortic valves close.
