Study Notes

  • Auscultation assesses heart valve areas.

Auscultation Areas

  • Aortic Area: Second right intercostal space at the sternal border.
  • Pulmonic Area: Second left intercostal space at the sternal border.
  • Tricuspid Area: Fourth left intercostal space at the sternal border.
  • Mitral Area (Apex): Fifth left intercostal space at the midclavicular line.

Normal Heart Sounds

  • Normal heart sounds includes $S_1$ and $S_2$, described as "lub" and "dub."
  • $S_1$ is associated with mitral and tricuspid valve closure and marks the start of systole.
  • $S_2$ is associated with aortic and pulmonic valve closure and marks the start of diastole.

Abnormal Heart Sounds

  • Abnormal heart sounds include $S_3$, $S_4$, murmurs, and clicks.
  • $S_3$ occurs in early diastole during rapid ventricular filling; heart failure indicator in older adults, normal in young.
  • $S_4$ occurs in late diastole due to atrial contraction against a stiff ventricle, often indicates ventricular hypertrophy or ischemia.

Electrocardiogram (ECG)

  • ECG graphically represents the heart's electrical activity.

ECG Waves

  • P wave represents atrial depolarization.
  • QRS complex represents ventricular depolarization.
  • T wave represents ventricular repolarization.

Intervals and Segments

  • PR interval measures the time from the start of atrial to ventricular depolarization.
  • QT interval measures the time from the start of ventricular depolarization to the end of ventricular repolarization.
  • ST segment measures the time from the end of ventricular depolarization to the start of ventricular repolarization.

Normal ECG Values

  • Heart Rate should be 60-100 bpm
  • PR interval should be 0.12-0.20 seconds
  • QRS complex should be 0.06-0.10 seconds
  • QT interval should be 0.36-0.44 seconds

Common ECG Abnormalities

  • Arrhythmias represent irregular heart rhythms.
  • Ischemia is indicated by ST segment depression or T wave inversion.
  • Infarction is indicated by ST segment elevation and Q waves.
  • Conduction Blocks represent delays or blocks in the electrical conduction pathway.

Cardiac Cycle

  • The cardiac cycle has two main phases.
  • Systole: Ventricular contraction and ejection of blood.
  • Diastole: Ventricular relaxation and filling with blood.

Key Events

  • Ventricular Filling: Blood flows from the atria into the ventricles.
  • Atrial Contraction: Atria contract to complete ventricular filling.
  • Isovolumetric Contraction: Ventricles contract with no change in volume.
  • Ventricular Ejection: Blood is ejected into the pulmonary artery and aorta.
  • Isovolumetric Relaxation: Ventricles relax with no change in volume.

Pressure and Volume Changes

  • Ventricular Pressure: Increases during systole and decreases during diastole.
  • Ventricular Volume: Increases during filling and decreases during ejection.
  • Aortic Pressure: Rises during ventricular ejection and declines during diastole.
