Study Notes
Abdominal Regions and ECG
ECG Waveforms
- The ECG waveform represents the electrical activity of the heart
- A normal ECG waveform consists of:
- P wave: Atrial depolarization
- PR interval: Time between atrial and ventricular depolarization
- QRS complex: Ventricular depolarization
- ST segment: Period of ventricular contraction
- T wave: Ventricular repolarization
- QT interval: Time between ventricular depolarization and repolarization
Abdominal Quadrants
- The abdominal cavity can be divided into four quadrants:
- Right upper quadrant (RUQ): Liver, gallbladder, right kidney
- Left upper quadrant (LUQ): Stomach, spleen, left kidney
- Right lower quadrant (RLQ): Cecum, appendix, right ureter
- Left lower quadrant (LLQ): Descending colon, left ureter
Abdominal Organ Localization
- Organs in the abdominal cavity can be localized to specific regions:
- Epigastric region: Stomach, pancreas, duodenum
- Umbilical region: Small intestine, transverse colon
- Hypogastric region: Urinary bladder, uterus (in females)
- Iliac regions: Iliac fossa, ureters
- Lumbar regions: Kidneys, adrenal glands
Test your knowledge of the abdominal regions, ECG waveforms, and organ localization. Learn about the different quadrants, organs, and their locations. Quiz yourself on the basics of ECG readings and waveforms.
