Match each classic electrocardiographic (ECG) description to its corresponding cardiac condition.

  • Progressive lengthening of the PR interval until a QRS complex is droppedMobitz type I (Wenckebach) atrioventricular block
  • Sawtooth baseline flutter waves, often with a regular ventricular responseAtrial flutter
  • Delta wave with a shortened PR interval and widened QRS complexWolff-Parkinson-White syndrome
  • Diffuse ST-segment elevations with concurrent PR-segment depressionsAcute pericarditis

Cevap

Mobitz type I block presents with progressive PR lengthening and a dropped QRS; atrial flutter shows sawtooth waves; Wolff-Parkinson-White syndrome features a delta wave and short PR interval; acute pericarditis is marked by diffuse ST elevations and PR depressions.
Each listed ECG finding is a pathognomonic hallmark of its respective condition. Mobitz type I involves progressive AV node fatigue (Wenckebach). Atrial flutter generates macroreentrant circuits leading to sawtooth waves. WPW syndrome creates early ventricular depolarization via an accessory pathway, visible as a delta wave. Acute pericarditis causes diffuse subepicardial inflammation, reflecting as widespread ST elevations and PR depressions.

Adım Adım Çözüm

1
Analyze each electrocardiographic description provided in the left column.
Identified four distinct textbook patterns: Wenckebach periodicity, sawtooth baseline, pre-excitation features, and diffuse inflammatory changes.
Recognizing classic ECG patterns is foundational to linking them to their corresponding physiological or pathological causes.
2
Correlate the identified ECG patterns with the specific clinical diagnoses provided in the right column.
Matched the patterns to Mobitz type I block, atrial flutter, WPW syndrome, and acute pericarditis respectively.
This establishes the definitive diagnostic link required to complete the matching task.
