Figure 3From: Ozone co-exposure modifies cardiac responses to fine and ultrafine ambient particulate matter in mice: concordance of electrocardiogram and mechanical responsesTypical mouse electrocardiogram and arrhythmia count during exposure. A. Typical mouse ECG during normal sinus rhythm and B. a non-conducted p-wave (NCPW) - represents a sudden loss of conduction from the atria to the ventricles. C. Non-conducted p-waves were significantly increased only in mice exposed to UFCAPs + O3. Values are mean ± SEM. p < 0.05; *significantly different from FA, Δ significantly different from UFCAPs alone, □ significantly different from O3 alone (n = 6).Back to article page
