[|Human|] The results from an EKG I had done and I am not sure what it all means.  here is what the report says:Rate  70    Sinus RhythmPR    168   Probable Left Atrial AbnormalityQRSD  88  Low Voltage In Frontal LeadsQT   441   Borderline T Abnormalities, Inferior Leads-AXIS-P   73QRS   40T   -8
[|AI|]  Rate of beating of heart normal 60-100sinus rhythm-A sinus rhythm is any cardiac rhythm where depolarization of the cardiac muscle begins at the sinus node. It is characterized by the presence of correctly oriented P waves on the electrocardiogram (ECG). Sinus rhythm is necessary, but not sufficient, for normal electrical activity within the heart. Image result for pr interval In electrocardiography, the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarisation) until the beginning of the QRS complex (the onset of ventricular depolarisation); it is normally between 120 and 200ms in duration. Axis is normal you have to study vectors for its inferior leads are leads representing inferior was of hear, borderline abnormality is not significant poor placement of leads can result in low voltage
