It seems likely that the symptoms you describe “pins and needles all over your face and a vibrating feeling in your right arm” are not due to a transient ischemic attack (TIA). IIt seems likely that the symptoms are due more to anxiety than a TIA. The other problem (SVT) should be analyzed carefully. First, you should determine the type of supra ventricular tachycardia (SVT) because there are several types of SVT: sinus tachycardia, atrial flatter/fibrillation, “roaming pacemaker” and nodal type of SVT. Therefore, an ECK and its professional interpretation is the first diagnostic step. An SVT can be due to a primary problem in the heart or to another reason other than the heart. You can check your thyroxin level in the blood because hyperthyroidism can cause SVT. Anxiety can be also a reason for some types of SVT, but other reasons should be excluded first. Beta-blockers and verapamil are the most frequently used drugs for treating SVT. Your blood pressure should be also regularly checked. You can consult a cardiologist about your heart problem.
