David H. Spodick (1927 – 2019) 300

David H. Spodick (1927 – 2019) was an American Cardiologist.

Clinician, researcher, educator, and administrator in cardiovascular medicine for over 50 years. World renowned for his work in pericardial diseases and electrocardiology research, diseases of the atria and interatrial conduction abnormalities and cardiovascular physical examination

Spodick, a pioneer in the study of the pericardium, described the classic four-stage evolution of electrocardiographic changes with pericarditis, including ST elevations and PR depressions in 1973/1974. He is eponymously affiliated with Spodick sign in pericarditis (1974) and the Spodick sign of aortic stenosis (1976)

…it is remarkable that clavicular transmission of aortic murmurs seems to have been neglected, while auscultation over the carotid artery has become a clinical ritual. Yet murmurs are nearly always greatly attenuated over the carotid artery, even to the point of disappearance.

Medical Eponyms
Spodick stages of pericarditis (1974)

Pericarditis is classically associated with ECG changes that evolve through four stages.

  • Stage 1 – widespread STE and PR depression with reciprocal changes in aVR (occurs during the first two weeks)
  • Stage 2 – normalisation of ST changes; generalised T wave flattening (1 to 3 weeks)
  • Stage 3 – flattened T waves become inverted (3 to several weeks)
  • Stage 4 – ECG returns to normal (several weeks onwards)

NB. Less than 50% of patients progress through all four classical stages and evolution of changes may not follow this typical pattern.

Spodick stages of pericarditis (1974)

Spodick sign in acute pericarditis (1974)

…the electrocardiographic registration of atria1 injury in acute pericarditis is analogous to that of the stage 1 ventricular subepicardial injury in that each follows the orientation of its respective normal recovery (T) wave. Since most atrial tissue lies posteriorly, to the right, and relatively cephalad of the ventricles, the orientation of a vector of generalized atrial injury (AP-R) would be expected to be to the right and superior (as shown by the frontal plane AP) and also posterior. The predominant P-R segment depressions across the precordium document the posterior component. Because of these P-R segment deviations, it is of practical importance in acute pericarditis to consider the T-P segment to be the electrocardiographic base line to avoid mistaking P-R segment depression for S-T segment elevation.

Spodick sign in stage 1 pericarditis
ECG of a 42-year-old man diagnosed with acute idiopathic/viral pericarditis. ECG represents Stage-1 pericarditis with diffuse PR-segment depression and ST segment elevation (except leads V1 and aVR where PR elevation is noted). Rhythm strip from lead II represents PR depression, ST elevation with slightly downward sloping TP segment (Spodick sign as depicted by blue arrow). Spodick sign is often best recognized in lead II as in this ECG illustration. [Chaubey VK, Chhabra L. 2014]

Spodick sign in aortic stenosis (1976)

Auscultation of aortic stenosis murmur over the mid-clavicle

Clavicular transmission of aortic valve murmurs was investigated in 15 consecutive patients. In all patients, transmission to the clavicle of aortic systolic murmurs was detected both by auscultation and by phonocardiographic studies.

Clavicular auscultation regularly discloses aortic valve murmurs. The aortic systolic murmurs are consistently propagated to the clavicle, where they are usually conspicuously amplified. Aortic systolic murmurs are less frequently transmitted to the carotid and subclavian arteries, where they are usually considerably attenuated. Clavicular auscultation appears to be more rewarding than the traditional search for transmission of aortic murmurs to the carotid artery.
