What could cause this weird blood pressure and arrhythmia?

Hello, I'm a 21 year old male, 6 feet tall, and weigh 150lbs. I'm pretty healthy but I do have anxiety/stress issues and started taking Zoloft 50mg 2 weeks ago. Over the past month, my heart has seemed erratic! My resting pulse is around 55-65bpm, but minimal activity such as walking or cleaning seems to push it to 100bpm. My blood pressure seems to be rising too, I think my average I've taken over the past few weeks clocks in around 130/80. Also, I had 2 EKGs done and 48 hour holter and nothing was found but a few ectopic beats.

Because of my anxiety, I've also started focusing on my heartbeat constantly so it always feels like its beating hard. Could this all be anxiety? Even when not stressed, I'll suddenly notice my heart rate go up.

Thank you!

I meant magnesium, B vitamins and vitamin C are required in greater quantities during times of stress. :)

I personally had sudden heart rate increase (in my case up to 300 bpm), high blood pressure and anxiety due to magnesium deficiency.

Deficiency of magnesium, B vitamins and vitamin C are required in greater quantities during times of stress.
Magnesium is called the anti anxiety mineral and B vitamins are called the anti stress vitamins.

I also wanted to add I've experienced on a few occasions random palpitations. Sitting at work at a desk my HR was 120 for no reason at one point. My heart also feels like its 'flip flopping' at times.
