the claim

Extracellular potassium concentration significantly affects heart rate and conduction velocity

the verdict
COMMON KNOWLEDGE
Legacy classification; evidence review pending
Recorded sources
no sources on either side

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that extracellular potassium concentration significantly affects heart rate and conduction velocity?

Extracellular potassium concentration fundamentally determines the resting membrane potential of cardiac cells, thereby directly dictating cardiac automaticity, heart rate, and electrical conduction velocity as established physiological principles.

Verdict: COMMON KNOWLEDGE · 0 sources for, 0 against · Last checked

The analysis

The effect of extracellular potassium on cardiac resting membrane potential, excitability, heart rate, and conduction velocity is a foundational and universally taught principle of cardiovascular physiology and biophysics. Therefore, it falls under common knowledge, requiring no specific literature citation.
