Electrocardiograph parameters of <i>cd8</i>^−/− mice adoptively transferred with CD8⁺ cell from <i>ifnγ</i>^−/−<i>pfn</i>^+/+ or <i>ifnγ</i>^+/+<i>pfn</i>^−/− and infected with the Colombian <i>T. cruzi</i> strain.

1<p><i>cd8</i>^−/− mice were: NI, non-infected; <i>T. cruzi</i>, infected with 100 bt forms of the Colombian <i>T. cruzi</i> strain 15 days after adoptive cell transfer (AdT) of CD8-enriched cells (≥98%), obtained from IFNγ-deficient (<i>ifnγ</i>^−/−<i>pfn</i>^+/+) or Pfn-deficient (<i>ifnγ</i>^+/+<i>pfn</i>^−/−) mice.</p>2<p>ECG parameters were evaluated using the following standard criteria: (i) heart rate (monitored by beats per minute (bpm), and (ii) the variation of the P wave and PR, QRS and corrected QT intervals (QTc), all measured in milliseconds (ms). ART, arrhythmia; AVB1, first-degree atrioventricular block; AVB2, second-degree atrioventricular block.</p>3<p>This table represented accumulated data from three independent experiments, with 3 to 5 mice/group in each experiment.</p>4<p>Significant differences:</p>*<p>, <i>p</i><0.05 - between the values for <i>cd8</i>^−/− noninfected and <i>T. cruzi</i>-infected mice;</p>#<p>, <i>p</i><0.05 - between the values for <i>cd8</i>^−/− non-reconstituted and <i>cd8</i>^−/− reconstituted and infected with <i>T. cruzi</i>.
