Different arrythmias: They come from different chamber ( upper vs lower) . Changes in BP and cardiac output depend on cardiac function , heart rate and and timing. Atrial fibrilation may decrease cardiac output about 15%. In ventricular tachycardia, BP and co will decrease more if it is long enough to become unstable.
