Article Title: Augmented Ouabain-Induced Vascular Response Reduces Cardiac Efficiency in Mice with Migraine-Associated Mutation in the Na + , K + -ATPase α 2 -Isoform

doi: 10.3390/biomedicines11020344

Figure Lengend Snippet: Temporal alignment between the second time derivative of aortic blood flow, ECG, and blood pressure traces allowed for the calculation of systolic time intervals. Upper panel includes blood flow through the ascending aorta (black line) and its 2nd time derivative, i.e., acceleration (gray line). Lower panel includes mouse ECG lead I with depicted Q, R, and S waves (black line) together with arterial blood pressure measured in the aortic arc (gray line). Black arrow indicates the dicrotic notch on the blood pressure trace, i.e., closure of the aortic valve. Preejection period was defined as spanning from the beginning of the Q wave to opening of the aortic valve, i.e., Q wave to the first peak of the second time derivative of aortic flow. Left ventricular ejection period was defined as spanning from the opening to the closure of the aortic valve, i.e., spanning from the first peak of the second time derivative of blood flow to the dicrotic notch. Systolic duration was defined as the sum of the pre-ejection period and left ventricular ejection time.

doi: 10.3390/biomedicines11020344

Figure Lengend Snippet: Baseline in vivo parameters and cardiovascular variables of all wild-type and α 2 +/G301R mice were similar. One wild-type mouse injected with vehicle had an uninterpretable ECG recording and, thus, was excluded in systolic time interval calculations. Data were compared with an unpaired t -test or a Mann–Whitney test where appropriate.

Article Title: Phenylephrine-Induced Cardiovascular Changes in the Anesthetized Mouse: An Integrated Assessment of in vivo Hemodynamics Under Conditions of Controlled Heart Rate

doi: 10.3389/fphys.2022.831724

Figure Lengend Snippet: A schematic for the experimental setup. Mice were anesthetized with isoflurane, and probes to monitor the cardiovascular parameters were implanted: (i) solid-state pressure catheter was inserted through the common carotid artery and placed in the arcus aorta, (ii) transit-time flow probe was mounted on the ascending aorta to measure cardiac output, (iii) bipolar electrodes were placed at the right atrium for cardiac pacing, (iv) mice were intubated endotracheally for mechanical ventilation, (v) ECG needle electrodes were placed on all four limbs to monitor heart rate and ECG parameters, and (vi) throughout the surgery and protocol, mice were placed on a homeothermic blanket system with a rectal probe to maintain core temperature.

Figure Lengend Snippet: Representative electrocardiograms (lead I) recorded prior to and after both the first and second pacing sessions for the vehicle (A–C) and phenylephrine groups (D–F) . Black arrows indicate P waves with consecutive QRS complexes, thus, describing sinus rhythm before and after electrical pacing of the heart. (G) There were no differences between the mean PR interval between vehicle and phenylephrine groups before and after both pacing sessions ( P = 0.92). (H) No differences in width of QRS complex were seen between the vehicle and phenylephrine groups ( P = 0.47). Data were compared with two-way ANOVA, n = 5.
